Quizplus · Accepted Answer

The trichromatic theory of color vision, proposed by Young and Helmholtz, suggests that the human eye has three types of receptors sensitive to red, green, and blue light. This theory explains color blindness well because most color blindness is due to the absence or malfunction of one or more types of the color receptors. It does not, however, adequately explain the phenomenon of negative afterimages, which is better accounted for by the opponent-process theory.
