Color Vision: Trichromatic and Opponent Process Theories

Webb10 apr. 2024 · The trichromatic theory of color vision says that human eyes only perceive three colors of light: red, blue, and green. The wavelengths of these three colors can be combined to create every color on the visible light spectrum. This theory was first suggested by Thomas Young and later tested by Hermann Von Helmholtz.

WebbThe process of color vision starts in the retina according to the Trichromatic Theory. This theory was developed by Thomas Young and Herman von Helmholtz, and thus it is also called the Young-Helmholtz theory. In the trichromatic theory, they proposed that the retina is comprised of three distinct types of cones or color-sensitive photoreceptors.
