Piet Mondrian Composition with Red, Yellow, and Blue 1927



The greyscale version shows the yellow square to be almost equiluminant with the white space, which gives it a vibrant and quavering quality, as compared with the red and blue squares which due to their darker luminance appear more stable and grounded in their respective positions in the upper left and lower right corners. We notice that the smallest colored square, the blue, is also the darkest. Perhaps the red square needs to be bigger and longer in order to counterbalance the density of the small, dark, blue.

An insight into the nature of "Awareness."

At the moment, I'm learning a lot about the Feldenkrais method of bodywork, which I know Dylan has heard of from being in the same class, but may be too difficult to explain to people who haven't been exposed. Essentially, it's a theory of how best to form new habits in human beings. For a number of reasons, the founder of the method, Moshe Feldenkrais, decided that the physical movement, the mechanism over which we have the most concrete and willable control, was the best vehicle for re-patterning inner tendencies that might not be so much under our control. Students of feldenkrais are told that the goal in all of the movement sequences is "Awareness," and the lessons themselves are in fact called "Awareness Through Movement."

What does it mean? "Awareness?"

Feldenkrais explained it via negativa by giving the example of someone walking up the stairs. Unless he or she is paying attention, he or she will have only a generalized awareness of the exact number of stairs climbed. To count the stairs as you climb them would require a form of "awareness." Closer to a definition, perhaps. Similarly, we are engaged at all times in behavioral and perceptual activities which we can perform relatively well without requiring any awareness whatsoever. We can eat food without tasting it. We can talk without being aware of our vowel or consonant articulation. We can listen to music without registering contrapuntal patterns and repetitions over time. We can go to an art museum, see something with a bunch of pretty or unpretty colors, without any awareness of the objective relationships between colors, which, it could be said, are the contribution of any given artist which make him or her MOST WORTHY of the designation "genius." These people are creating structural frameworks which do not necessarily impose themselves on the perceptions of a spectator who hasn't been schooled or acculturated to view visual art with this type of awareness.

Mr. I's case is a perfect example of a situation in which someone has awareness forced upon them through deprivation. Mr I was obviously not unaware of the structural relationships between colors, and as a painter and lover of art, probably needed no such schooling. But if you or I were by some miracle allowed to experience his condition TEMPORARILY, and thereafter return to full color perception, we would be automatically primed for a type of color awareness we had previously taken for granted. As a result, we become much more engaged by and grateful for our peculiar ability to differentiate color in this way, and art, and LIFE, in general become a--for lack of a better word--more pleasing to experience.

The Feldenkrais bodywork is fashioned in the same vein on the principle that an increase in awareness of interrelations between structures (in this case, structures of the human body) corresponds to a decrease in general suffering, confusion and anomie, and that therefore is inherently desirable.

Colors are not as they seem



Alfredo Quevedo (in the style of Van Gogh), 2003, 24x24", acrylic on canvas


Some thoughts that pertain to this week’s readings:

I’m fascinated by two concepts and am hoping to marry them together in this (brief) blog post. In Arnheim’s texts, he discusses how the vivid qualities of color in paintings decay over time due to pigmentation and the natural circumstances under which they are shown. Paintings, as we see them today, are “lies.” We can never hope to gain the full experience of, for example, Renaissance Fresco paintings simply because of preservation and restoration issues.

But what struck me beyond that, when marrying these concepts with Livingstone’s concise history of theories of seeing, is maybe we also have a different way of seeing that people did several hundreds of years ago. The eye, as Livingstone mentioned, has been actively changing and modifying throughout the processes of evolution. On a scientific level, how much has the eye evolved in the last centuries? And on a cultural level, how are do receive stimuli from the world around us that would force us to see differently? So even if we were to find some way to time travel back to the Renaissance, we might still see completely different paintings than those who viewed them during their first reveal.

Reply to Danielle's Post

Danielle, I also was entranced by the Sacks piece. The account addressed the whole of Jonathan’s experience in a way that made me as the reader begin to envision the world as he perceived it. I thought it was interesting how his vision was not just a black and white version of what a normally sighted person sees, but a more challenged and confusing black and white version. He had reduced ability to distinguish shades and shapes. Arnheim explains in the chapter on color that humans can usually distinguish about 200 shades of grey. Jonathan did not seem to have that ability.
You also commented that you were surprised that when offered a possible cure, Jonathan refused. I thought this was interesting, but I was not very surprised. I have read a number of different Sacks essays and amazingly most of his subjects learn to live with and in some cases learn to love their shift in perception. Perhaps this demonstrates the extent to which out mind and our functioning can adapt and reorganize to cope with challenges. Sacks suggests that perhaps Jonathan’s brain reallocated certain areas for different functions, perhaps causing his stronger night vision and sharper long-distance vision.
I too was thinking about how different our perceptions of color may be. All of the readings asserted that color is not static, it depends on perception and context. It is constantly influenced by the surrounding colors and the ambient light. Although Livingston (I think) said that on average most people’s eyes seem to perceive colors in the same mechanical way it appears that our perception of color can still be very different. This seems like a question to continue to ponder, and one that will come up repeatedly as we read more about visual perception.

The painting becomes so much flatter and harder to read in black and white. There is so much more detail and depth in the shadows because of the color that is used, and when the painting is in black and white that quality of the painting falls away.

Assignment 1. Equiluminant Effects


"Ole Lukøje" by Nils von Dardel


Color Perception

Arnheim’s frequent interludes of awe and reverence for the perception of colors, while maintaining a work of systematic merit, demands a constant appraisal of the parts to the whole. However, there is hint of humanity about his work and while the constructs of color theory supply the necessary beams, I cannot help but sense that these beams are supporting an abstract of humanity.

Arnheim is fully aware of the difficulties of color perception- “most of the time the viewer cannot judge how much truth or a lie is being told (344).” But while he acknowledges that the world has material and life and spirit, Arnheim is acutely aware that each realm has a parallel form to the other. Color perception is not simply the product of inner dynamic fields, but instead contains tensions, balance and momentum just as it contains the static structural relations. We learn that the “identity of color does not reside in the color itself but is established by relation (362)”and further on,“ the web of interacting colors is created only by the eye, and this subjectivity—quite different than the sturdy objectivity of shapes—gives them the quality of apparitions.” I think it is quite fascinating how colors are so temperamental and how they are at once subjective and objective. I am reminded of Cezanne’s portraits and how the subjects quiver and vibrate simply in response to an outlining of blue. And while there may seem to be a discordant part, Arnheim reminds us that “ The traditional theory of color harmony deals only with obtaining connections and avoiding separations, and is therefore at best incomplete (350)” It is more than creating a unified whole; it is giving adequate shape to an intended content.

From Mr. I’s paintings post-accident, we discover that although Mr. I used known colors that theoretically and categorically worked together, the after effect was confusing to viewers who had normal color perception and even became a hesitant source for him. Despite the subsystems, the categories, the ordering of color, the resonance of color is profound. Mr. I found that color perception did not only affect his visual perception, but his “aesthetic sense, his sensibility, his creative identity…and now color was gone, not only perception, but in imagination and memory as well (35).” Mr. Nordby, a colorblind case prior to Mr. I, writes, “Although I have acquired a thorough theoretical knowledge of the physics of colours and the physiology of the colour receptor mechanims, nothing of this can help me to understand the true nature of colours (36).” The perception of color is profound in its ability to affect emotion and aesthetic sense. I think it fitting to close with Geothe, “Optical illusion is optical truth.”

Black and White Color


" BUT - I AM SO ABSOLUTELY COLOR BLIND ... I have been involved in all kinds of tests. You name it. My brown dog is dark grey. Tomato juice is black."

Jonathan's letter to Oliver Sacks baffled him. This was a man who had lived his whole life seeing normally but after a car crash was now viewing a black and white movie of his life and seeing through a built in zoom. Color is an everyday thing that is taken for granted except when its family movie night and you beg your mom not to rent Casablanca and instead rent the recently released movie Coraline.

It must be unbearably scary to wake up one morning after an accident, not even remembering the event and then have your world turn into a gray blur. For an artist to loose their sense of colors and for their paintings to become "unfamiliar and meaningless" must be debilitating. Not only did his own paintings change but he would not be able to dissect as Arnheim does, Matisse's painting Luxury, where he describes the spatial relationships due to color or the bright yellowness of the nude bodies in the image. He also would have no recognition of the yellow haired angel children in The Virgin with Santa Ines and Santa Tecla by El Greco. This very drastic and rapid change made Jonathan extremely depressed. He felt the world looked "dirty" and didn't even want to look at his own reflection in the mirror. His lost his desire to have sex because his wife was now "gray". He dreams turned gray and his memories had been drained of color. How would you feel if your whole world and life's work was now altered and possibly lost? When Arnheim quotes Poussin " The colors in painting are, as it were, blandishments to lure the eyes, as the beauty of the verses in poetry is a lure for the ears." it accentuates how Jonathan must have felt. He felt that nothing would ever be the same, and it wouldn't.

I found the scientific parts of these stories interesting but I was more drawn in by how people like Jonathan and Virgil dealt with their new way of life. A great deal of learning and readjustment was necessary. Just like in the other Sacks piece Virgil has to teach himself to see and understand what he had previously only felt. When he encounters the lathe and touches it he exclaims "Now that I've felt it I can see." Jonathan like Virgil takes baby steps. Virgil teaches himself how to see and what he is seeing in relation to what he has been blind to in his earlier life. Jonathan teaches himself how to continue living with a whole new vision. The different ideas that Jonathan creates to make himself more comfortable are fascinating. He starts eating black and white foods to avoid the foods that had once been red or green. He labels all his clothes and their colors just to make getting dressed in the morning easier. These everyday normal activities become a process for him. Activities and necessary tasks that were once done with ease were now a challenge. It made me think of the thousands of tasks we do everyday without reflection. Most significant to me was that his memories of color had vanished and consequently his history had changed.

Jonathan's desire to get back to painting was a huge part of his story. As an artist he lost "A sense that interweaves itself in all our visual experiences and is so central in our imagination and memory, our knowledge of the world, our culture and art." He wanted to pick up his brushes and pretend that nothing had happened. It was not that easy. His artist friends were telling him not to paint in color and that if he did no one would understand his paintings. Similar to Livingston's descriptions of when a color painting is photographed in black and white, Jonathan's paintings would also lack depth. Even his colleagues had given up hope on his ability to function as an artist. This didn't stop him. I admired his stubbornness. He started by creating a comfortable environment for himself. His made his studio into a palate of grays which he felt would communicate his experience to others. I thought this was a really good way to force people to see the way he did. After seeing a sunset one day it inspired him to teach himself to paint again but this time in black and white. He had wondered if anyone had ever seen the sunset the way he did. So he painted it. Painting became his therapy. It was his way of coping with the constant feeling of being alone. It also gave him the chance to show the world the exclusive image he saw.

For a while the processes of trying to get his eyes fixed was another thing that kept him sane. It must have been extremely hard to hope and get let down and know that his eyesight would never be perfectly restored. He might get one step closer but never fully "the same". Jonathan was living in fear. Many people encounter the fear that their life will never be the same again. Jonathan's fear however was starting to become reality. He was beginning to come to terms with the fact that he was colorblind and would most likely never be able to see color again. This pointed out to me ways that the body and the brain adapt while compensating for the great physical and mental losses we suffer as human beings.

The end of the story has a twist that I found unexpected. Jonathan was approached with a procedure that would possibly cure him and give him back his sense of color. He turned the idea down. His previously colorful world had transformed into a disgusting dirty gray world which had then turned into his final "uncluttered by color" world. He was finally embracing his black and white vision and saw it as unique. He had a whole new understanding of his situation. He finally had gotten himself to a place where he was settled and didn't want any more disruptions. While reading I anticipated a fairy tale ending where his vision would be restored but instead understood and appreciated his decision to remain untrammeled by any further changes.

I found the story sensational and mystifying. A man living his life is in a sudden car crash destroying one of his most precious senses as an artist, color. The ways in which Jonathan learns to cope with his situation and the little life tactics he invents were intriguing. His healing process was long and hard but resulted in a acceptance of his newfound self. He felt that his art keep him alive and gave him a new challenge everyday. He created paintings that people could relate to and opened their eyes to his world. He reconstructed his life and continued living it. When asked to if he wanted to see color again and possibly get his old life back he realized that black and white was his life. I am amazed at the mechanisms he created to change his perception of his self. One day picking out a shirt was easy and the next day impossible. How do you accept that ? He final realization was that he was getting a chance that no one else would.

The story reminded me of questions I would think about when I was younger. What does the person next to me see ? What does a dog see ? Is my blue her red ? Does he see my blue or does he have his own blue ?


Experiencing Light and Color

“The nature of light is a subject of no material importance to the concerns of life or to the practice of the arts, but it is in many other respects extremely interesting.”
Thomas Young’s quote humoured me as I began this week’s readings. It sparked thoughts about how important light really is to our lives. Light has so much to do with color as we have read in Livingstone’s early chapters and color impacts art in regards to aesthetics, for example take a black and white photograph or print and put it next to a fully coloured version of that same print and the images/ artwork look completely different and give the viewer different feelings about the work. I believe this is true especially with photography. Acquiring or not acquiring the proper light is essential to a quality photograph. You have to catch the right wave atop the present subject at the appropriate time of day, which brings the sun in to play. Depending upon the type of mood or angle you want to achieve light is important to color.
While reading Vision and Art a statement that Livingstone makes about the colors we see in butterfly wings, pearls, opals, hummingbird and peacock feathers, representing the diffraction of colors, also known as interference reminded me of the differentiation in the color of flames. When you turn on a gas stove the flames are a hue of blue. When flames are viewed on a larger scale they look orangish red in color. Granted the interference Livingstone is referring to is the tiny glare that is usually best seen from a spherical view, meaning the circumference of a pearl or the ocellus of a peacock feather. Can this interference of light be viewed differently or inaccurately? Livingstone states that most people have three cone types categorized by wavelength long, middle, and short also referred to by color red, green and blue. What if a person is looking at a pearl or butterfly wings and their yellow cone is impaired, how would this affect the neuron signal? This person would not be able to distinguish the yellow wavelength, so what would he or she see no color at all in place of the yellow or simply a more intensified experience of blue and red? At least this is true for me yet then again we all see things differently. I was wondering if this change of color in flames due to interference as well or is it due to some other properties related to the refraction of light or none of the above?

Color and Emotion

Reading The Case of The Colorblind Painter, I was struck by the notion of the fragility of sight. This was not simply because Mr. I happened to lose his color vision, but because, after reading about the complexities of vision in Margaret Livingstone’s book, it seemed inherent to the mechanism. The eye, comprised of so many connecting devices each integral to the ability to see, seems like it could fall apart at any moment. Though Mr. I suffered injury to his brain and not his eyes, the result of the loss of a significant element of his sight has the same implications. Indeed, what struck me about Mr. I’s case was the spectrum of damage done to his reality by the loss of his color vision; a point truly driven home by Sacks: “The ‘wrongness’ of everything was disturbing, even disgusting, and applied to every circumstance of daily life. He found foods disgusting due to their greyish, dead appearance and had to close his eyes to eat.” This example illustrates the scope of the impairment, and convinces the skeptical reader that this case is not one limited to sight. Indeed, one could argue that the damage done to his perception of his environment is the shallowest of the layers of his issue. What is being described throughout the first half of the article is the significant emotional trauma that Mr. I endures during the early days of his colorblindness. The idea of “wrongness”, usually so shunned by psychologists who dislike viewing their subjects and their realities as falling into categories of “right” and “wrong”, is the sole way to describe Mr. I’s perspective on his condition. Mr. I must also suffer with the knowledge of this wrongness; denied the blissful ignorance of those born colorblind who only know the world one way. Though he can no longer visualize color, it is the comparison between then and now that gives him added discomfort.
Meanwhile, the first chapters of the Livingstone book describe in physiological terms how sight is achieved, citing photoreceptors, incandescent and luminescent light and photons as agents of how neurotypical people can perceive the world. The mechanism itself is rather astounding; like many basic functions there is much more to it than meets the eye (please excuse that horrid pun). After reading those chapters and the Sacks article, I found myself wondering how the two extremes; the emotion involved with seeing and the mechanism that begets it, are so nicely reconciled in neurotypical individuals to create the functional, colorful atmosphere in which we live our daily lives? In other words, with the understanding that through millennia of evolution we are no longer surprised that the sunset is red and purple, how did emotion become integrated into our physiological devices of perception? Returning to Mr. I, a deficit in his sight had far-reaching implications in his life, all emotional and mental in nature. Unlike Virgil from last week, Mr. I had no difficulty negotiating his physical place in his environment, rather, he had trouble relating his environment to himself. It seemed that color dictated his relationship to almost all elements around him; food, art, music, sex, etcetera. How did this connection develop? Livingstone touches upon a related subject; saying that personal background and experience influences they way in which one perceives the world. Influences, but not dictates. However, in another chapter, she refers to Picasso’s The Tragedy, saying, “The colors carry the emotional content of the painting; the melancholy blue color is highly symbolic.” It is interesting to think about where our conceptions of emotion concerned with color originated, and how essential they truly are to the act of simply living. As demonstrated by Mr. I’s condition, emotional stability is nearly reliant on perceptual stability.

Music

What I found incredibly interesting about these readings was the connections to music through the scope of color perception. In, what was for me, one of the more clear examples in Arnheim’s text is the idea that color like notes in a key cannot be assumed to fit together just because the are complimentary in some way. Music is not about the sum of twelve notes, placed together because they sound good inherently, but the “giving [of] adequate shape to an intended content.”(349) Color must be handled the same way, though Arnheim quotes many proponents of design, color must be used to give shapes their....shape. Colors applied to shapes gives them meaning and personality, we have a visceral reaction to their hues. Also similar to music different palettes can go out of fashion, some colors may not be used to accent certain shapes in one period or another, however they as a concept are always applied to give “shape to an intended content”.
Sacks touches upon this theme with Mr. I, who cannot bear the everyday necessities (food, etc) because they lack the color markers to inform him of their use and importance. In a world suddenly without color Mr. I cannot see the forest not for the trees, but for their lack of shape. Sacks mentions that music became very dull for Mr. I, as he used to have “intense synesthesia” which allowed his brain to translate music in to images and colors. With his sudden color blindness there was nothing, his experience of music was with out form. In this case instead of using music as a structure to which we can compare the schema of color; color, or the lack of it, informs one mans entire perception of another sense he once enjoyed. Though the sections are brief, both authors alighted in me the idea that hearing and seeing are related in our ability to perceive one medium or the other. When Arnheim mentioned the structure of music, the theories of color cleared up for me entirely, even the idea of music that I have aided me greatly in sorting out the more obtuse ideas about color arrangements. Where as in Mr. I’s example I was able to relate and see the real issue he could have with not seeing the colors of the music. This is because I too posses a kind of synesthesia, music for me creates stories and some times I find that the colors of a scene in front of me leads me to create my own music to accompany it (which also makes me wonder, as Winnie mentioned, our cross-over between filmic viewing and the real world). If there were no colors to inform my music or no knowledge of music to accompany my study of color, I would be at a severe loss. To understand one, it would seem, is to have a platform on which you can base the understanding of the other. Both are ambiguous, both are subjected to categorization- but as Arnheim mentions the Western music notation system does not take in to account hundred of pitches that the human ear can hear, as a color wheel does not include all of the colors we can interpret on any given day. Both music and color are two different ends to a similar means, they both posses a power through which they can shape our perception (aurally and visually), through skilled composition and contrast. They are the meat to the bones of our lives.

Color

Although the Arnheim reading was full of interesting information and completely upended most of my conceptions about color and light and how they’re related, the one thing that stuck with me most was his description of a particular experiment in which “children were presented, for example, with a blue square and a red circle. They were asked whether a red square was more like the square or like the circle. Under such conditions, children up to three years of age chose more often on the basis of shape, whereas those between three and six selected by color. Children over six were disturbed by the ambiguity of the task, but more often opted for shape as their criterion” (335). I was interested by the explanation provided. According to Werner, the youngest children are mostly influenced by motor behavior and so the “graspable” shapes are more influential, while children between the ages of three and six have more developed visual characteristics and are drawn to colors rather than shapes. Werner also claims that children over the age of six gravitate back to shapes because of cultural influences. They are being “train[ed] in practical skills, which rely on shape much more heavily than on color” (335) and thus turn their attention to what will be most useful. It was this particular theory that most caught my attention. I have to wonder if this phenomenon really is a matter of cultural influences or if it could be a manifestation of another stage of brain development. I think that it is quite possible that cultural emphasis on practicality is responsible for a choice of shapes over colors, but I think it’s equally possible that it’s more of a biological development. After all, as evidenced by other species’ ability to perceive more or less color, it seems that perception of shapes is more relevant to a species’ survival. If that’s the case, then it would make sense that as a person moves closer to maturity, to being self-sufficient, they would naturally focus more on the aspects of a situation that could influence their survival.

On another note, Sacks’s story of the colorblind painter struck me in a few ways. At first, the idea of food becoming inedible because the colors were wrong seemed strange to me. After all, it would still smell and taste the same. But then I remembered this one time when my dad made green oatmeal for St. Patrick’s day. The oatmeal tasted perfectly normal. Logically, there shouldn’t have been a problem. But nobody ate it because it just looked wrong. Granted, in this case the food coloring actually made it look moldy, but I have a feeling that if he had turned it blue I would have had a similar problem. There’s a saying (which is often quoted on the Food Network) that “you first eat with your eyes” and I think Mr. I is living proof of this. I also wonder if this is something he has gotten over with time. Sacks describes how he has adapted to many aspects of his condition and how he would not regain his ability to see colors if given the choice, but I am curious as to whether he still prefers to live on black and white food.

Livingstone’s discussion of luminescence also reminded me of Mr. I. Sacks explains that he, along with many achromatopsia patients, not only saw the world in black and white, but that it was “wrong” and “dirty” and “impure” (7). I wonder if this has anything to do with luminescence. As Livingstone points out, most of the time when a color painting is photographed in black and white it loses much of its luminescence and tends to fall flat. I wonder if this is exactly what was going on with Mr. I. After all, he had much less of a problem with things that were already in black and white, things that were either designed in a way so that the luminescence carried through into the grayscale or things that had already lost that quality, whereas looking at something in color, something that hadn’t already been filtered for him, was disturbing. This is purely speculation, of course, but the dull pictures in Livingstone’s book, such as the black and white representation of Monet’s Impression Sunrise, had a flatness and wrongness that reminded me of what Sacks describes in his article.
