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 theory and/or color:
“Dont confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.”
—Martin H. Fischer (18791962)
“He could jazz up the map-reading class by having a full-size color photograph of Betty Grable in a bathing suit, with a co- ordinate grid system laid over it. The instructor could point to different parts of her and say, Give me the co-ordinates.... The Major could see every unit in the Army using his idea.... Hot dog!”
—Norman Mailer (b. 1923)
