Quizplus · Accepted Answer

The trichromatic theory of color vision, also known as the Young-Helmholtz theory, proposes that the retina contains three types of color receptors (cones) that are each most sensitive to either red, blue, or green wavelengths of light. These three color signals are then combined to create the perception of all colors in the visible spectrum.
