  • color circle: a chart in which complementary colors (or their names) are arranged on opposite sides of a circle
  • A color wheel or color circle is either: * An abstract illustrative organization of color hues around a circle, that show relationships between primary colors, secondary colors, complementary colors, etc.
  • A circle with different colored sectors used to show the relationship between colors
  • Rotating wheel with 3 or more translucent color filters used to display sequential color on single imager light valve based projection devices.

  • Michel Eugène Chevreul (31 August 1786 - 9 April 1889) was a French chemist whose work with fatty acids led to early applications in the fields of art and science. He is credited with the discovery of margaric acid and designing an early form of soap made from animal fats and salt.
  • A physicist who published a theory of colour contrasts which influenced many art movements including the Impressionists, Post impressionists and Orphic cubism.

Definition: pointillism |ˈpwa n tēˌyizəm; ˈpointlˌizəm| noun a technique of neo-Impressionist painting using tiny dots of various pure colors, which become blended in the viewer's eye. It was developed by Seurat with the aim of producing a greater degree of luminosity and brilliance of color. I add: The light collected by our digital camera's lens is filtered into Red, Green, and Blue components. Each component of light is directed to it's own sensor chip. The way these are combined leads to an imitation of the stream of light flowing to our eyes by the objects being viewed. The stream of light is more like a collection of individual particles coming to our eyes. Each particle is called a photon. It has a unique wavelength, that we perceive as a specific color. Pointillism attempts to use the physics of vision in the real world of individual photons.

What led Seurat to using points of clear color? Scientific background and influences During the 19th century, scientist-writers such as Michel Eugène Chevreul, Ogden Rood and David Sutter wrote treatises on color, optical effects and perception. They were able to translate the scientific research of Helmholtz and Newton into a written form that was understandable by non-scientists. Chevreul was perhaps the most important influence on artists at the time; his great contribution was producing a color wheel of primary and intermediary hues. Chevreul was a French chemist who restored old tapestries. During his restorations of tapestries he noticed that the only way to restore a section properly was to take into account the influence of the colors around the missing wool; he could not produce the right hue unless he recognized the surrounding dyes. Chevreul discovered that two colors juxtaposed, slightly overlapping or very close together, would have the effect of another color when seen from a distance. The discovery of this phenomenon became the basis for the Pointillist technique of the Neoimpressionist painters. Chevreul also realized that the 'halo' that one sees after looking at a color is actually the opposing, or complementary, color. For example: After looking at a red object, one may see a cyan echo/halo of the original object. This complementary color (as an example, cyan for red) is due to retinal persistence. Neoimpressionist painters interested in the interplay of colors made extensive use of complementary colors in their paintings. In his works Chevreul advised artists that they should not just paint the color of the object being depicted, but rather they should add colors and make appropriate adjustments to achieve a harmony. It seems that the harmony Chevreul wrote about is what Seurat came to call 'emotion'. According to Professor Anne Beauchemin from McGill University, most Neoimpressionist painters probably did not read Chevreul's books, but instead they read Grammaire des arts du dessin, written in 1867 by Charles Blanc, who cited Chevreul's works. Blanc's book was targeted at artists and art connoisseurs. Color had an emotional significance for him, and he made explicit recommendations to artists which were close to the theories later adopted by the Neoimpressionists. He said that color should not be based on the 'judgment of taste', but rather it should be close to what we experience in reality. Blanc did not want artists to use equal intensities of color, but rather to consciously plan and understand the role of each hue. Another important influence on the Neoimpressionists was Ogden Rood, who also studied color and optical effects. Whereas the theories of Chevreul are based on Newton's thoughts on the mixing of light, Rood's writings are based on the work of Helmholtz, and as such he analyzed the effects of mixing together and juxtaposing material pigments. For Rood, the primary colors were red, green, and blue-violet. Like Chevreul, he stated that if two colors are placed next to each other, from a distance they look like a third distinctive color. Rood also pointed out that the juxtaposition of primary hues next to each other would create a far more intense and pleasing color when perceived by the eye and mind than the corresponding color made by mixing paint. Rood advised that artists be aware of the difference between additive and subtractive qualities of color, since material pigments and optical pigments (light) do n

I'm teaching my sixth graders the names of the colors in Latin. They have a mini project to make a color wheel labeled in Latin. Here's mine, done in acrylic paint and gold leaf. I'm thinking of introducing the Four Beast-Angels: Man, Bull, Ox and Eagle to the corners of this page, and then inking them with the related tertiary colors. What do you think?
