Color Theory
In color theory, two colors are called complementary if, when mixed in the proper proportion, they produce a neutral color (grey, white, or black).
In roughly-perceptual color models, the neutral colors (white, greys, and black) lie along a central axis. For example, in the HSV color space, complementary colors (as defined in HSV) lie opposite each other on any horizontal cross-section.
Thus, in the CIE 1931 color space a color of a particular "dominant" wavelength can be mixed with a particular amount of the "complementary" wavelength to produce a neutral color (grey or white).
In the RGB color model (and derived models such as HSV), primary colors and secondary colors are paired in this way:
- red and cyan
- green and magenta
- blue and yellow.

Famous quotes containing the words color and/or theory:
“The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera—and himself.”
—Daniel J. Boorstin (b. 1914)
“By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
—Abraham Lincoln (1809–1865)
