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:
“Surely the day will come when color means nothing more than skin tone, when religion is seen uniquely as a way to speak one’s soul; when birth places have the weight of a throw of the dice and all men are born free, when understanding breeds love and brotherhood.”
—Josephine Baker (1906–1975)
“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)
