Question

How does the trichromatic theory of color perception differ from the opponent-process theory? The trichromatic theory of color holds that all possible perceived colors are combinations of three stimuli, while opponent-process theory holds each perceptible color has a matching stimulus. The trichromatic theory of color holds that color perception occurs primarily in the retina, while opponent-process theory holds that color perception occurs mainly in the visual cortex. The trichromatic theory of color holds that white light is split into primary colors, while opponent-process theory holds that component colors are merged into three different signals. The trichromatic theory of color holds that three fundamental colors are encoded by corresponding cones, while opponent-process theory holds that three different cells split two colors each.

Answer 1

• The trichromatic theory explains colour vision phenomena at the photoreceptor level.

• The opponent-process theory explains colour vision phenomena that result from the way in which photoreceptors are interconnected neurally.

Explanation:

• Trichromatic hypothesis prompted the speculation that typical shading vision depends on the action of three sorts of receptors, S (short frequency), M (medium-frequency), and L (long frequency) cones each with an alternate pinnacle affectability.  
• The opponent-process hypothesis expresses that no two individuals from a couple can be seen in a similar area, which clarifies why we don't experience such hues as "pale blue-yellow" or "reddish green". This hypothesis additionally assists with clarifying a few kinds of shading vision deficiency.  

• A trichromatic hypothesis is that our eye recognizes with red, green and blue receptors and procedure these to perceive color. Opponent process hypothesis is that we have a color receptor and opposing color receptors and see that shading by the balance between the two.

• The opponent-process theory is a model to explain how the mind perceives color. While the trichromatic theory postulates that color is first received via waves of light entering red, blue, and green cones in the eye, the opponent-process theory explains how these cones are neurally connected.
