The trichromatic theory best explains color vision at the receptor level, and the opponent-process theory best explains color vision in the thalamus and the visual cortex.

Question

Quizplus · Accepted Answer

The trichromatic theory, also known as the Young-Helmholtz theory, states that there are three types of color receptors in the retina that are responsible for detecting color - red, green, and blue. The opponent-process theory, on the other hand, proposes that color vision is based on three opposing pairs of colors - red vs. green, blue vs. yellow, and black vs. white - that are processed in the thalamus and visual cortex. Therefore, the statement is true that the trichromatic theory best explains color vision at the receptor level, and the opponent-process theory best explains color vision in the thalamus and the visual cortex.
