The trichromatic theory of color vision is based on the idea that the retina contains __________
A) three classes of cells that alter their rates of firing according to color.
B) three types of rods that respond to different saturation levels.
C) rods, cones and a third type of cell called a muon that, depending upon the hue, stimulates different combinations of cones to fire.
D) three types of cones that respond maximally to one of three colors - red, green or blue.

Question

Quizplus · Accepted Answer

The trichromatic theory of color vision proposes that the retina contains three types of cones, each of which responds maximally to one of three colors: red, green, or blue. By combining the signals from these three types of cones, the brain is able to perceive a wide range of colors. This theory has strong empirical support and is widely accepted in the field of vision research.
