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, suggests that we have cone receptors in our eyes that are sensitive to red, green, and blue light. The opponent-process theory, on the other hand, suggests that color vision is based on three pairs of opponent colors: red-green, yellow-blue, and black-white. Therefore, both theories are complementary and explain different aspects of color vision.
