Describe the trichromatic theory of color vision.

Answer:

Responses may vary but should include some or all of the following information: The trichromatic theory of color vision states that humans have three types of receptors within the eye that vary in sensitivity to different light wavelengths. The three receptors are usually associated with the colors red, green, and blue. People can see a variety of colors because the eye mixes colors together by varying activity among the three receptors.
