Theories of Color Vision

Explanations for color vision have a long history dating back to the early Greeks. The development of the trichromatic theory of color vision was one of the earliest formal theories, but Ewald Hering later noted that trichromatic theory could not account for all aspects of color vision such as the fact that some colors do not occur together at the same time. For example, people do not see yellowish-blues and reddish-greens. You can learn more about these two theories of color vision in the following:

• Opponent-process Theory of Color Vision
