Greek Drama and Aesthetic Archeology

Monday, December 13th, 2010

Modes of minimalist thinking often find fullest expression in Greek stories. Layers of culture are stripped back to the origins of Western discursive and narrative approach. Cutting through layers of history and culture to expose its root means cutting through all narrative structures to find their essence.

Minimalism forces upon us a kind of archeology of style. Idiosyncratic and stylistic flourish often fail when exposed to the archeology of minimalism. The Greeks allow for a minimalist narrative in large part because their stories are so close to the archetypal source there is little extra. Often, Greek stories provide the bare minimum of context before moving forwards with a primal and archetypal tale.

Sophocles, in many ways, deals in pure archetype. Some of this is based on the stories he chooses to tell. Focus on the parent child relationship, as in the Oedipus cycle, strikes to the core of the human experience. This essential story is amplified by the narrative structures available to him. In his day, drama was seen as consisting of two actors and a chorus. Because of this constraint, he was forced to fit the complexity of human experience into a dichotomy. It forced dialog and paired monologue instead of conversation.

This very contained world is in sharp distinction to the plays of Euripides. Not only is Euripides willing to call into question the very power dynamics underlying society, he does so through a revolution in the dramatic form. The addition of a third actor increases, logarithmically, the complexity of potential storytelling dynamics.

In The Bacchae, for example, the same actor who plays the priest also plays the god. The actor who plays the mother plays the son. The king is played by the same actor who plays the servant. In this way, Euripides is able to question social politics through the very structures of narrative. If the king and the servant are manifested through the same soul, through being played by the same actor, what does that say about power and control in society?

What implications does this have for those of us who would design these worlds? Are there lessons we may learn? What are these plays speaking that would inform us, in a useful way, as builders and designers of the worlds these plays would inhabit?

First, it would serve us well to look at the structure of these stories. As designers, we are first and foremost visual storytellers. The story we are telling comes from the text. If it is a minimal or archetypal text, then perhaps we ought to look for that archetype in our design.

But what kind of minimalism is this?

The minimalism of Sophocles is different than that of Euripides. Do the characters have a single, unchanging, soul? Do they have a shared soul which manifests different aspects? Are these writers even minimalist?

A lot of evidence indicates that these texts are little more than the equivalent of an operatic libretto. In short, we are missing the music, the songs, and the choreography which these plays originally had and which made them far more of a spectacle than common thinking often allows of them today.

It was recently discovered that Greek statuary was painted in vibrant colors. Perhaps, then, neo-classicism and classical minimalism are nothing more than aesthetic anomalies founded on a misinterpretation of historical evidence. Minimalism, as an aesthetic concern, may indicate a far more modern line of thought than we typically consider it to be.

All of this concerns us as designers of theatrical worlds. Scenery, props, lighting, costumes, and music are all implicated by our asking of these questions. Our results are determined by our answers.

On Inspiration

Monday, May 10th, 2010

The question of inspiration is one that is central to any creative person. While inspiration might not be thought of in the moment, its lack is one of the most terrifying things to be felt in a creative pursuit. Writer’s block is probably the most commonly heard version of this, but the problem can plague anyone working creatively.

While there is no surefire cure for the problem, there are numerous strategies we can employ to not only prevent it from arising in the first place, but to create a plethora of creativity such that we never approach such a situation. For those of us working on deadlines, like an opening night, we quite literally do not have time to be bogged down with writer’s block. We must simply get to work.

Inspiration can come from any direction and often can hit us by surprise when least looking for it. While we can not ensure that we will be struck by inspiration we can create situations that will increase the chances that we will. In short, we can create our own luck. We may not know what bit of stimulus will spawn a creative flurry, but we can be open to new sources of stimulus, new ideas, new images, new sounds, new people, and new art. Ninety-nine percent of all this will just be enjoyable diversion, but that one percent is invaluable. That one new painting, or new restaurant, or random conversation will spark a creative fire that could not have happened without it.

This kind of luck requires two discrete actions on our part. The first is access to novelty. We must actually experience these things. We must go to the museum, or the movie, or the concert, or the library. This is the easy part. Every day we are exposed to novelty if we are open to seeing it. And that is the second, deeper, and more difficult aspect of this. We must be open to new experiences. We must train ourselves to see things in a new light. Inspiration often comes from seeing the familiar in a new and unique manner. We must take each moment as the new, unique, and novel thing that it is.

I find exposing myself to new art, new music, new people and so forth to be mandatory as an artist. Seeing the old as new, reframing the familiar as the novel, is a powerful exercise to increase novelty in your life and thus increase your luck in discovering the right spark for that next project. Situationists like Guy Debord used techniques like the derive to give new meaning to the familiar environment of their well worn urban streets.

While the SI looks a bit old fashioned from the perspective of the early 21st century, their techniques, or variants on them, can be profoundly powerful. Breaking with routine has an amazing effect on the creative mind. That break in routine can be through something wholly new, or it can come from turning the familiar into the novel.

I find music to be a powerful source of inspiration. While I will certainly listen to a single album, score, or a general genre, one thing I love to do is put my entire music collection on shuffle and hit play. The juxtaposition of a Mozart symphony with minimal techno with gangsta rap presents me with a kind of aural derive drifting between radically different musical styles, causing my mind to reprogram connections as it finds similarities between previously disparate songs.

I remember, years ago, going to a poetry event somewhere in the East Village. There were people reading works, and poems on the walls to be read. There was music, and wine, and shifting lighting. Perhaps a bit more raucous than what many people think of when they think poetry event. But then this is New York. There was a station set up with a typewriter. Guests were encouraged to sit down and write for five minutes. It was timed. When the timer was started, in addition to the lighting and music for the general room, a boom box was played, flashlights were shined on the person, and several books were read aloud right in their ears. The effect of this was to wholly shortcircuit the thinking rational part of the brain and leave only the creative generative part able to function in the sensory barrage. Manufactured Inspiration.

One of the simplest sources of inspiration I find is in living life. Simply being open to experience and aware of one’s surroundings and interactions with others can provide a deep and rich palette upon which to draw. Unfortunately too many people sleepwalk through their interactions in life. With a focus on what could have been or what might be they fail to actually take the time to appreciate what is. Being in the present is where the creative power lives. Cultivating presence of mind is an invaluable exercise to build one’s creative muscles.

The quest for inspiration is eternal. As we move through experiences our perception of different inputs as sources for inspiration will shift and change. It is necessary to be vigilant and create opportunities for inspiration that change with our changing needs.

Abstract Realism

Friday, May 7th, 2010

There is an assumed dichotomy, when discussing works of art, between abstract pieces and realistic works. Realistic might be substituted for naturalistic, but the basic dichotomy reigns. I have discussed abstract minimalism quite a lot in this space. The counterpoint to abstract minimalism is not realism or naturalism but abstract realism.

Art, by it’s very nature, demands of the creator that choices be made. An object, event, idea, image, plot, and so forth are all framed. The frame might be literal in the sense of a classical painting, or it may be metaphoric through the use of language. In all cases a human experience is reified and placed within a frame. Art is the abstraction of reality.

To understand how fundamental abstraction is to art we should look, not to those considered abstract like Mondrian or Beckett, but to those considered realists like Ibsen or Caravaggio. In understanding the abstraction inherent in naturalistic works, this will lead us to a deeper understanding of and appreciation for those works more traditionally considered abstract. Even photography, by the nature of framing an image, abstracts our experience of reality before we even get to issues of color or focus. Walker Evans, about as naturalistic a photographer as has ever shot a roll of film, is highly abstract. Not so much in what he includes exactly, but with regards to what lies outside the frame. Through his images we have a limited understanding of a particular view of reality. A deep and rich understanding of that piece of the real, but a piece nonetheless.

Ibsen is a fantastic example of linguistic framing. He takes a story and distills it into the formalism of the three act play. Life is abstracted from the glorious non-linear mess that it is into a tight and controlled sequence of events. Act 1, Introduction. We, the audience, are shown the major players, ideas, and themes that will run their course throughout the play. Act 2, Conflict. We see the characters, ideas, and themes evolve and come into conflict. Act 3, Resolution. The conflict comes to an end perhaps through some transformation of the people, ideas, and themes. This may all sound familiar.

Should we choose to abstract this structure further we would do well to look back at Hegel and his dialectic. His thesis, anti-thesis, synthesis follows the same rhythmic pattern as the three act “well made” play. Once we understand that structure we can apply our understanding to any work and see that the distinction between realist and abstract work is a surface distinction at best. Good works that exist as temporal art (music, theater, opera, dance) all share this rhythmic structure. The form may be infinitely varied but the underlying structure is the same.

In the visual realm, rhythmic structure is replaced with proportion. When I looked at minimalism earlier I used Mondrian as an example. His work throughout his career was an exploration of proportion, though the form was multi-varied. Rothko is a painter whose work is focused on proportion almost to the exclusion of anything else.

The rigor needed for minimalism points to the necessary abstraction in any work of art. It is impossible to include everything in a work of art. Reality is the only experience that is not abstract.

Mondrian, or Rothko, are wonderful examples of the formalism of proportion exercises. We can look to Caravaggio, a so called realist, to better understand the formal structure of proportion. At the time he was active, his work was derided for the realistic style he employed, especially with regards to the painting of religious figures. While his realism is indeed impressive, and arguably unparalleled in the history of painting, it is at the more abstracted level that his works take on their true power. His sense of proportion, in terms of color, composition, and contrast, are impeccable.

As close to reality as some of Caravaggio’s works get, they are the product of clear and decisive choices at every level. From general composition, to the finer details of relative value between figures, to the color palette, we are looking at an abstracted space. Foreground and background, or depth of field to return to the world of photography, play a critical role in solidifying a well proportioned image.

Working as a lighting designer for live performance, I am concerned with both the rhythmic structure of the temporal work and issues of proportion. Foreground and background play a critical role, as do relative light and darkness, color, and other issues of contrast. At the same time, I must deal with these issues over time as the stage picture constantly changes. Temporal Rhythmic Proportion is a synthesis of the structures of temporal art and static art. It is the basis of what we do as visual artists for live performance. Navigating the ever shifting compositional needs through time is the primary concern of the lighting designer.

As naturalistic as a work might be, we are moving through an abstracted space bounded by abstracted time. From Beckett to Ibsen we navigate an abstraction of reality. Fundamentally understanding abstract space allows us to do so with full efficacy and powerful results.

The Affirmative No

Monday, May 3rd, 2010

I was given two pieces of advice about how to evaluate potential projects when I was in graduate school. Both came from successful designers and with me just starting out figured I would incorporate this advice as best I could. The first piece of advice had to do with criteria for evaluating projects. There are three reasons to do a show; the art, the people, or the money. So long as any two of those three were present, the job was worth taking. The second was much more straightforward, take every job you can since you have no idea where it might lead.

Over time, the criteria I use to evaluate projects has gotten more refined, but in truth, more personal. Increasingly, I find myself drawn to projects that fully meet my creative artistic needs. If I am doing a job just for the money, the money better damn well be worth it. Otherwise the project must support my artistic needs.

In these lean economic times finding work has been much more difficult than it has in years past. As a function of this I was on the path for a while of taking a few projects for which I had no artistic connection because I felt I needed the money. The more I thought of this, the more these projects would bother me. Finally, I realized what it was.

As a freelance designer I do not have the luxury of sitting in my studio and creating wholly out my mind. I do not get to generate the project. Rather, I am asked to do a project and I can either accept it or turn it down. While I learned a lot during my years of saying “yes” to everything, I am increasingly learning the value of “No.” This is not the No of negation. Rather this No is an affirmation of the aesthetic viewpoint I want to propagate in the world.

By saying No to projects that I do not wholly believe in I am saying Yes to the projects that I truly want to work on. The more I do this the more I find it has less to do with the specific pieces themselves as it does the people involved and the final product being created. In short, I have discovered that there are only two reasons for taking a project, the People and the Art. Follow those two things and the money will take care of itself.

There are a hand full of directors who I will work with at the drop of a hat and without hesitation because I believe in the work they do. One of these, a long time friend, has a very different aesthetic than I do when it comes to lighting. The process can often be quite a struggle for me as I overcome my own ways of seeing to get behind his eyes. Nonetheless, I believe in his work and larger vision strongly enough that this has sufficient artistic merit for me to take the project.

Working for the money, all you have to fall back on when things get difficult is the thought of that paycheck. Working for the Art and for the People keeps in clear view that what you are working for is something larger than yourself. It is, in fact, bigger than everyone involved.

As Moss Hart has famously said: “I have had many successes and many failures in my life. My successes have always been for different reasons, but my failures have always been for the same reason: I said yes when I meant no.”

Color Theory Basics – The Effect of Lamp Type on Color

Friday, January 29th, 2010

For the last installment in my series about Color Theory we will look at how Color and the Perception of Color is affected by the source of the light, or the Lamp Type. Anyone who has spent any amount of time working with a mixed package of discharge sources and conventional lights knows that getting them to work together can present significant challenges. Further, the qualities of light (direct vs. indirect or spotlight vs. flood lights) can effect how we perceive the exact same color from the exact same lamp. It is useful to have a basic working knowledge of these ideas so that you can approach your lighting plot from a stronger position.

The Effect of Source.

Most lighting for live performance utilizes Incandescent lights. These are variations on the same bulbs found in any household or workplace. There is some kind of metal filament which is encased in a glass globe. Electricity is passed through the filament and the heat from that is discharged in the form of light. As much advancement as we have seen, these are very simple technologies, and not too far from fire. We burn an object and it creates light and heat. Oldest trick in the lighting book.

Because we are basically operating on the same system as our caveman ancestors, the colors are very similar. These bulbs make a warm soft glow. Our eye is particularly attuned to this range of colors and while the full spectrum of visible light is present in this “White” light, there is a preponderance of light in the Red and Amber range. This makes the light emitted from such bulbs appear “natural” and “looks good” on any range of skin tones.

An alternative to the incandescent bulb is the Discharge Source. A common discharge bulb used in Film, TV, and some live performance is the HMI. Rather than burning a piece (or pieces) of metal, the glass globe is filled with various gasses which, when excited by the introduction of electricity, emit light in rather precise wavelengths. Fluorescent bulbs work this way as well. Depending on the mixture of gasses, the color will be different. Neon is a commonly used gas as are Sodium, Mercury, and others.

How do these work?

Electricity causes a shift in the orbit of electrons around the nucleus of an atom. In these more agitated states, the atoms can absorb some amount of additional electrons. At some point the atom returns to its normal state and the electrons return to their standard orbit. When this happens the extra electrons are released from orbit in the form of photons. The wavelength of the photon (or as our eyes and brain would say, Color) is determined by the type of atom we are dealing with. The Earth’s atmosphere, for example, has a mixture of gasses which, when averaged, produce light in the medium Blue range. As the sunlight filters through the atmosphere, exciting the gasses in our atmosphere, the light emitted from the restored atoms averages out to Blue. Color mixing and physics!

Because the mixture of gasses produce different colors of light, the use of color filters on these lights will produce different effects than when used on incandescent lamps. We commonly see these differences when using Followspots. While the majority of our lighting rig might be incandescent spotlights, the followspots are very likely Xenon, or some other gas. Thus we must balance the color of the spots to blend with the rest of the lighting. The difference in lamp type in these situations is a primary cause of Missing Color Syndrome and a leading need to understand Color Correction. Similar situations arise through the use of many Automated lighting instruments. This is why many will include a CTO option in their color mixing and/or color wheel options.

Not only is the actual color different based on what kind of bulb we have, but the perception of the color can change based on whether the light is direct or indirect, a spot or a flood. Direct light from spotlights are the most common in live performance. Be they ERSs, PARs, Fresnels, or other, all of these lights produce a hard direct light. The light comes, more or less, straight our of the bulb in a concentrated fashion and hits an object. Because of this, the light is seen as being very present. Under certain conditions you can see the geometric shape of the cone of light itself.

Contrast that with floodlights like Mini-10s, Far Cycs, or Mercury Vapor Gym lights, and you see that the quality of light is much softer and more diffuse. We still have the directionality and the hardness, but we lose the geometry. While these can be useful for filling a volume of space efficiently with light, they are not so good for giving that light a clearly defined presence. As the light has less presence so too does our perception of the color. While you might want this effect, it can make colors appear muddy or unclear. You get illumination, but it can be hard to get a real sense of the light itself as an entity.

Taking another step back we have indirect sources like Softlites and Bounce Light. While you can bounce any kind of light off of any kind of surface, typically one uses a spotlight to bounce off a White surface. This is a technique common in Film and TV, but rare in live performance. The quality of light is similar to that of an overcast day. There is illumination, but it is shadowless. The light wraps around and enfolds objects. While it is a beautiful quality of light, one must very carefully consider their color choices here. The light itself is so recessive that getting basic visibility necessitates clear and considered color choices.

While the default choice for most designers is some version of the incandescent spotlight, there is a whole world of options available, each of which provides the designer with myriad opportunities for using Color in new and exciting ways. I would encourage you to explore the whole range of lamps and qualities of light to see how it effects your perception of Color.

Thank you for reading this series. I hope you found it useful.

Color Theory Basics – Gray

Monday, January 25th, 2010

No discussion of Color or Color Theory on this blog would be complete without an exploration of the color Gray. If I was being truly rigorous and precise it would have been part of the discussion on Saturation and Chroma as Gray is, by definition, non-chromatic light. For personal and pragmatic reasons I chose to place Gray in it’s own section. The subtlety of this range is such that it requires mastery of the other basics before it can really be approached.

I find it amazing to me how many people, when I mention that Gray is my favorite color, tell me it either does not exist or cannot be created with light. In a certain sense this is true. Gray, like White, is a perceptual effect caused by the mixture of all wavelengths of light. However, it is exactly this perceptual effect that I find so rich, varied, and interesting. Curiously these same people who tell me the color does not exist, or can not be created, then go off to start up their computers with apple logos on them and watch as their RGB screens produce a Gray on Gray opening window as it loads the operating system. The inability of many to properly mix Gray, does not deny its existence. Rather, it points out how difficult the color is to achieve.

For a more poetic exploration of Gray read my essay Ten Thousand Shades of Gray. For the purposes of this essay we will be looking at a more systematic approach to utilizing Gray-scale lighting to achieve dramatic effects. Reading my previous essay on Color Mixing, if you do not have much practical experience in that regard, is necessary for understanding the ideas contained in here.

First lets look at Gray from an RGB mix. This is how your computer screen makes Gray. It is how the sticky note upon which I am writing this essay is perceived as Gray by me. Mixing Gray from RGB gives you tremendous control. Just as there are many different Hues of chromatic colors, there are just as many Hues in Gray. You can have a Blue-Gray or a Green-Gray, a Warm-Gray or a Cool-Gray. The subtle distinction and changes in how you mix your Gray, in this case I am imagining a Cyc, make costumes and people pop from that background or recede into it.

All of this control however is deeply time consuming. Just like any precise color mixing (CMY matching Gel colors for example) you have to be patient and clearly look at what you see before you. Mixing a good Gray gets down to adjusting lighting levels by one percent at a time until you reach the final mix. You can not rush this process or the work ends up sloppy and you walk away saying things like “Gray can not be mixed with theatrical lights.”

Not only is the work inherently time consuming but the focus must be precise. It is virtually impossible to do work in a Gray scale on a Cyc without a boucedrop. The light must be even enough that the edges of the color mixing are totally imperceptible. While this is true for all color mixed Cycs, an improperly focused RGB drop in Gray tones, is deadly. Take your time to plan through your drop lighting. Take your time to focus. Take your time to mix the colors. When you have taken the time to properly think through all of this the results will be truly satisfying.

Strict RGB (G250, L090, R80 for example) is one way to achieve these effects. But there are other ranges of colors that can be used. CTBs from about 1/2 CTB to double CTB work quite well. Similar colors like L161 can also be used to good effect. A warm CTB like R3202 can mix well with a color like L161 to create a nice range of cool and warm Gray. Add in a little CLR or Lavender and you can easily mix a wide range of Gray. While your options will be much more limited, you gain the benefit of saving a lot of time mixing the colors as they naturally fall into a Gray palette from the beginning.

Lavenders, mentioned above, can be useful. So too can pale Cyan, especially if you want to cast a more Dominant quality to the light. Cyan can be a wonderful option when used in a palette of dominant blues. However it runs the risk of appearing too chromatic against more recessive colors. Specifically recessive Blues. One must be very attentive to the color choices made when working in Grey or else you simply end up with an unsaturated palette. While that too can be engaging, if it is not the intent, then it is not right.

Let us now return to the Woman-in-a-Red-Dress. While we decided last week to have the entire stage go Red on her entrance, the director thought the move was too blunt. She would prefer to have the woman set against the environment in a striking way. Here is a perfect opportunity for Gray. We light the scene in cool Gray tones throughout. Then, when the Woman-in-a-Red-Dress enters we do a slight shift on the Cyc to increase the Green a point or two. We use our L202 Backlight and R3202 Frontlight for the scene. The effect is one where the complementary colors of Green(er) Cyc and Cool(er) Backlight separate the dress from the rest of the environment. The warm(er) Frontlight helps to pull the dress out even more. This will give us precisely the effect our director wants. A brilliantly illuminated figure which appears to stand outside the rest of the action and an otherwise unified space.

This essay up to now has assumed you were using incandescent lights with color filters to create your Gray environment. However, there is an entire world of lighting beyond those bulbs with incandescing filaments. Many discharge sources work very well to create Gray worlds. Metal Halides and HMIs are a prime example. HMI is daylight and Metal Halide is in that family but pushed towards Green. Fluorescent tubes can be an exciting way to explore Gray. Mercury Vapor lights come close but run the risk of being too Green. They can be amazing in the right balance, but you should use them wisely.

The world of Gray is an amazing, and often underutilized, tool in the lighting designer’s tool kit. While it takes a large degree of discipline, dedication, and rigor, the payoff can be astounding. I encourage you to explore this world and the full richness it provides just as you would more chromatic color ideas.

I hope you found this useful. Please take any new ideas and start experimenting. In my last post for this series I will be exploring The Effect of Lamp Type on Color. Stay tuned.

Color Theory Basics – Additive and Subtractive Color Mixing

Friday, January 22nd, 2010

From our discussions of Hue we learned the basic properties of what the human eye perceives as color. In later essays we looked at how some of these principals might be applied in practical theatrical settings. Until now we have left out one of the most fun parts of working with color. Color Mixing.

Color Mixing is where we really get to test our knowledge of light and color and see what we know. We have already done some mixing through our exploration of Missing Color Syndrome but that has all been reactionary. We were trying to solve problems, not create environments. Now we will look at color and color mixing as a proactive tool in the designer’s tool kit.

As we recall from our basic color wheel there are three Primary Colors of light; Red, Green, and Blue. Those can then be mixed into the three Secondary Colors of light; Magenta, Cyan, and Amber. Obviously by varying the amount of each color, or mixing in slight amounts of the third Primary you can get the full range of possible Hues out of these three colors. Needless to say, you need not limit yourself to six heavily saturated Hues. You can see from the image on the left the basic principals of Additive Color Mixing with light. It is called “additive” because we might take a Red light and ADD Green to it to make Yellow.

Wait. What?!?!

For those new to mixing light and color this can take some time to wrap your head around but this is how the process works. Red+Green=Yellow. Green+Blue=Cyan. Blue+Red=Magenta. All but the first make logical sense to a brain trained to understand colors in terms of pigments. But we must unlearn that knowledge if we are to truly embrace the power of color.

So Additive Color Mixing comes about when we have two or more Hues mixing together to create a third Hue. This has traditionally been the most common form of color mixing in live performance. However, with the advent of Automated Lighting we have seen a radical shift towards a second method for mixing colors. That is Subtractive Color Mixing.

In order to fully understand subtractive color mixing we need to back up a moment and review. What the human eye perceives as White light is really just the phenomenon of the eye seeing a roughly even distribution of all the colors in the visible spectrum. With that in mind let us look at a typical lightbulb. When the light is on, it emits light across the full spectrum of visible light. If we put a Red (say G250) color filter in front of the light we are not “turning the light Red.” Rather, what we are doing is blocking off, or filtering out, every wavelength of light except those in the Red range.

Now Subtractive Color Mixing gets a little complex, for those new to it please bear with me, the pay off is definitely worth it. When dealing with Subtractive Color Mixing we actually need to invert our understanding of Primary and Secondary Colors. If Red, Green, and Blue are our Primary Colors for Additive Mixing, then Cyan, Yellow, and Magenta are our Primary Colors for Subtractive Mixing. That’s three different sets of Primary and Secondary Colors (when we include the Red, Blue, Yellow of pigments) we have to keep in our brain.

Confused yet?

Subtractive Color Mixing actually subtracts in two ways. First is the method described above where it subtracts all the wavelengths NOT in the color filter. So when we put a Magenta filter in front of a light we are removing all the wave lengths that are not Magenta. Now, remember that Magenta is comprised of Red and Blue. So when we put that filter up it is as though we were using a Red and Blue filter together. If we want to make Red we need to get rid of the Blue.

How do we do this?

If we recall our Primary Color Wheel for light we remember that Blue and Yellow are opposite colors. By adding Yellow to the Magenta we are in essence canceling out the Blue and leaving us with Red. If an algebra equation would help, we are trying to solve M+Y=??? We know that Y=(-B) and M=(B+R) so the equation could be rewritten (B+R)+(-B) or B+R-B=R. Clearly we don’t need to go back to High School Algebra to understand color, but it can help to wrap your brain around the processes involved in Subtractive Color Mixing when first encountering these ideas.

Many Automated Lighting systems utilize Subtractive Color Mixing in their color functions in order to give the designer a full range of colors to work with in their projects. I would like to explore two commonly used accessories. The first is the Wybron CXI and the second is the Morpheus Color Fader. Both of these devices use Subtractive Color Mixing (known in the industry and CMY Color Mixing). Wybron’s technology uses two strings, one with various saturations of Cyan and Magenta, the other with various saturations of Magenta and Yellow. Morpheus uses three strings of color. One each for Cyan, Magenta, and Yellow. The strings range in an even transition from Clear to full saturation.

While the Wybron will give you 432 colors, the Morpheus will give you millions of color options and a degree of precision not available with the Wybron units. Further, because the Wybron units employ discrete pieces of gel strung together one cannot do live color fades without stepping through various unwanted and potentially unpleasant colors in the process. This is the same problem encountered when using a traditional color scroller. The Morpheus technology on the other hand allows for smooth color transitions live on stage. In addition, because it employs three color strings, the designer can vary the speeds at which the different colors crossfade. So if one wanted to fade from Red to Blue, you could have the Yellow fade out faster and the Cyan fade in slower thus passing through Magenta rather than some strange unwanted color.

In a lighting world where advanced automated systems are becoming more and more prevalent, the designer must have an implicit knowledge of these technologies and the color theories underlying them. Even if your work does not typically use color changing technology of this sort, you will inevitably find yourself in situations where you will have to grapple with them. Forewarned is forearmed. Solving problems is a lot more interesting than sitting around trying to decode complex color theory. Especially when the clock is ticking ever closer to opening night.

If we return to our Woman-in-a-red-dress we immediately see the benefits of these theories and their related technologies. Rather than spending tons of time sifting through gel books in the studio and comparing them to the fabric swatches, we might simply point a few of our moving lights, or color changing crosslights, at the Woman-in-a-red-dress on her entrance. From there we can fine tune the color to precisely match the tones of her costume and skin. Having this control is especially nice when the fabric gets dyed a slightly different Hue than we originally planned for.

Perhaps the whole stage goes Red upon her entrance in a bump. Then the rest of the stage does a color fade to our recessive Blue while she walks out and takes control of the scene backlit in Red, with crosslights perfectly matched to her skin tone. Being able to have just the right mix of Yellow and Magenta to make the dress truly shine takes skill, patience, and attention to craft.

Knowing the uses and distinctions between Additive and Subtractive Color Mixing is a powerful practical application of lighting Color Theory. In later posts I will be exploring Gray and The Effect of Lamp Type.

Color Theory Basics – Dominant and Recessive Colors

Friday, January 15th, 2010

Close your eyes.

Imagine yourself hiking through the hills. You have been walking amidst some trees for a while and come to a clearing. It’s a few hours after noon and you notice the sun has begun its progression towards the Western horizon. In front of you are more trees crisply limned in the mid-afternoon sunlight. You look a further on towards the mountains in the distance and notice that these same trees and brush appear bathed in a pale lavender light.

You may now open your eyes.

The human eye, having evolved over millions of years with these lighting effects present, has learned to process certain colors as being in either the foreground or the background. The crisp 5700K sunlight is an indicator to our eyes that something is in the foreground. A soft and delicate lavender is an indicator to our eyes that something is far off in the distance. The former dominates our field of view, while the latter recedes into the background.

Beyond evolution, Dominant and Recessive Colors have another interesting property as well. Dominant Colors tend to hold their integrity as colors when in the presence of other colors. Recessive Colors willingly and readily mix in with other colors to either disappear entirely or form third colors.

Probably the clearest example of a dominant color would be Cyan. No matter what you do, it will always be Cyan. You can add Blue to make it more Blue, or Green to make it more Green, but it will always be Cyan, dominant and in the foreground. At the opposite extreme we have Lavender. No matter what other color you turn on, your Lavender will do its level best to mix with that color and recede into the background.

Knowing that some colors are inherently perceived as being in the foreground, while others are perceived as being in the background, gives us tremendous opportunity to sculpt our stage picture and focus the eye where we want it to go.

To reiterate, a Dominant Color will push a figure forwards while a Recessive Color will cause a figure to recede into the distance. The example of ABT’s lightplot, from our discussion on Missing Color Syndrome, applies here as well. The R70 in the Backlight is a Dominant Color which, being Backlight, helps to push our dancer towards us and sculpts the outline of their body. The R51 Frontlight allows us to see them, but the color quickly receeds into whatever else we might have turned on, perhaps some L201 Shins. In this way we can use Frontlight for facial illumination without sacrificing the sculptural qualities of our Backlight and Sidelight.

Backlight and Sidelight are Dominant Angles. They are very powerful and present in a way that a Recessive Angle like Frontlight is not. Using Dominant Colors in Dominant Angles and Recessive Colors in Recessive Angles, as we see in the ABT Repertory Plot, can create striking effects.

Let us now explore these ideas with our Woman-in-a-Red-Dress. Having lit her in Magenta (dominant) Backlight and Lavender (recessive) Frontlight we have created a look whereby our ingenue is front and center in our visual focus, her face is clearly lit and her body is sharply outlined against the scenery. We now have to light the other people in the scene who are watching her. Perhaps we use the same Frontlight system but turn on the Congo Blue (recessive) Backlight. They will all be clearly visible, but our eye will naturally be drawn to the Woman-in-a-Red-Dress. This is true even if she is way upstage of them!

The use of Dominant and Recessive Colors, in conjunction with Dominant and Recessive Angles, helps to create a sense of focus for the eye in much the same way that a camera can put foregound or background figures into focus. In short, we control our depth of field through these tools and thus compose our stage pictures to reflect the key objects we should be looking at in a given light cue.

With these distinctions in mind it could be easy to question why we would use Recessive colors at all. If we want to create powerful and dynamic stage pictures, then everything should be Dominant. Right? It is healthy to be wary of Recessive Colors. One could easily design a palette which looks great in the studio but, when put into practice, makes it impossible to see anyone clearly. The key here is to use colors judiciously and correctly.

At the same time, while it is good to embrace bold Dominant Color choices, do not get carried away. The eye gets tired. Further, you could find yourself having trouble losing focus on a secondary area of the stage. Be bold, but know when to temper your passions.

Remember the first rule of lighting; everything is relative.

One could construct a plot out of all Recessive Colors (I have done it many times). Because some colors are more recessive than others you could create many of the same effects through using colors that are less recessive in the Backlight and more recessive in the Frontlight. There are plenty of delicate ballets and whimsical musicals which call for just such a color palette.

Knowing the distinctions between Dominant and Recessive Colors is a critical tool in composing our looks for the stage. If you missed my essays on Hue or Saturation and Chroma I would encourage you to go back and read them through. In later posts I will be exploring Color Correction, Gray, The Effect of Lamp Type, and Additive vs. Subtractive color mixing.

Color Theory Basics – Missing Color Syndrome

Monday, January 11th, 2010

Building upon ideas from our discussions of Hue and Saturation and Chroma we will now explore a phenomenon called Missing Color Syndrome. If you did not read the first two essays I would encourage you to do so as they provide foundational concepts which will be necessary to understand for this post to be of any real use.

Before I begin, I want to preface this essay by saying that this concept and the effects we are discussing here are some of the most difficult to understand through words. Writing about lighting color theory at all is a bit of a losing battle, but Missing Color Syndrome in particular only lands when you directly observe the problem, and the solution. I would encourage you to test these ideas and play around with different color combinations to see the different instances of these effects.

And now, on with the show.

Missing Color Syndrome is the name of the phenomenon that occurs when two lights with more saturated color media play against a less saturated or Clear light. The less saturated light takes on the quality of the shadow color of the more dominant light(s). The result is a light that does not look the way the designer intended it to. While this might be a problem for the unprepared, when we analyze the problem clearly, or even ahead of time, with the proper tools, we can bring greater awareness and precision to our color palettes for every show we light.

How does Missing Color Syndrome arise?

The human eye (or more accurately the human brain) has a propensity to create patterns. Add to that the evolution of the human eye to see what we know as the “visible spectrum” of light and you end up with a piece of technology that tries to see White light (or at least all three primary colors) in its field of vision at all times. Should we compose a look with only two of those colors, the eye will do its best to turn the least saturated light into that missing third color. If you use only Red and Blue, for example, the eye will desperately search for Green and will take liberties to turn non-Green colors Green if it has to.

Let’s return to our Woman-in-a-Red-Dress, once again, to see where this problem might arise. Perhaps our earlier choice of a G250 Frontlight was not the best. It toned her skin a too rosy pink and the director was interested in very natural skin tones for her actors. Further, the costume designer felt that while the color popped, his patterns and textures were lost. For our own reasons we decide against a true Red and choose a sympathetic color, Magenta. We put our L126 in a Backlight special and turn it on. It looks fantastic. Now to light her face. Excited by the Magenta we turn on our Frontlight and it looks a little Green. So we turn it up brighter. Still Green. By the time we have cranked it up to Full we do not notice the Green, but that fantastic Magenta halo effect is gone and she no longer looks like the stunning ingenue but rather like some too bright mannequin from a poorly lit department store.

This could be a disaster, but with our new found color tools, it is a solvable problem.

Returning to our Color Wheel we see that Magenta and Green are opposite one another. As we learned in our discussion of Hue, a shadow will take on the opposite color of its light. Because of this, when we put Magenta color media in front of one of the lights it makes the other light appear Green. This is not physics but physiology. How the human eye perceives something is wholly dependent upon the context.

To put it simply, everything is relative.

Now, one solution would be to put a Magenta color filter in our Frontlight. However, we already discussed the problems with heavily saturated Frontlight color and know that is not a viable solution. Returning to our discussion of Saturation we see that there are myriad options available to us to solve this problem without saturated colors. A Tint of Magenta is commonly known as Lavender. Further, Red is a sympathetic color to Magenta (and the same Hue as the dress). So in addition to a whole range of Lavenders we have many Pinks to choose from as well. We could use a warm Blue but it would need to be selected very carefully to avoid killing (or significantly altering) the dress color.

By using R53 (a very pale Lavender) instead of Clear we can have a huge impact. The Lavender, when set against the L126, will appear as White light. Because of the Lavender our eye is unable to make up the missing color and resigns itself to White. Our shadow color goes away and our look is preserved.

Missing Color Syndrome is most egregious in very colorful shows but can certainly arise in more monochromatic situations. The above case of Missing Color Syndrome is overt. A more subtle version of this phenomenon can be far more deadly. That is when we are working in a palette of Tints. Often it is not readily apparent what the trouble is because nothing is saturated enough to clearly see the missing color. All we know is that something doesn’t look right.

Missing Color Syndrome is often not caused by a single dominant color. Let’s say we have Pink and Blue Booms coming from either side. When we turn on our Clear Frontlight to fill out the figure we notice it taking on a Green tinge. This is due to the Pink and Blue acting in concert to create the shadow color of Magenta (the color Pink and Blue would make if mixed together).

Depending on the saturation of our first two colors the problem will need to be solved with varying saturations of our third color. If our Booms are L201 and G105 we may only need a very slight boost, perhaps an R53 or G109. If our colors are more saturated, like an R68 and L106, then we will need a much more saturated Tint to overcome the eye’s perception of the Clear light as Green.

We can turn this information around and use it to create striking color combinations in our palettes. Tom Skelton’s repertory colors for ABT use these very ideas to their advantage. There, the Backlight color is R70 and the Frontlight is R51. The Green Backlight contrasts strongly with the Lavender Frontlight (they are complementary colors). The effect is to push the Lavender (and the Blues as well) into a warmer and more inviting tone. Perfect for Ballet.

Understanding Missing Color Syndrome and how to cure it is one of the first practical applications of lighting Color Theory. If you missed my post on Hue or Saturation and Chroma I would encourage you to go back and read them through. In later posts I will be exploring Dominant and Recessive Colors, Color Correction, Gray, The Effect of Lamp Type, and Additive vs. Subtractive color mixing.
