Trichromatic Theory of Color Vision in AP Psychology

Definition

The Trichromatic Theory of Color Vision explains how humans perceive color through the presence of three types of cones in the retina that are sensitive to different wavelengths of light. These cones allow us to see a wide range of colors by combining signals from red, green, and blue.

Related terms

Cone Cells: Specialized cells in the retina that contain photopigments and are responsible for detecting and perceiving different wavelengths of light.

Opponent Process Theory:

A theory that complements the Trichromatic Theory by explaining how color vision occurs through opposing pairs (red-green, blue-yellow) at the neural level.

Color Blindness:

A visual condition where an individual has difficulty distinguishing certain colors due to abnormalities or deficiencies in their cone cells.
