primary colors

the basic colors from which all the various hues can be produced by mixing different combinations. Some investigators believe human color perception involves combinations of the three primary colors (i.e., blue, green, and red); others contend that yellow, violet, or both should be included because of visual color sensitivity peaks found at those wavelengths.
