Trichromatic Theory

Definition

The Trichromatic Theory is a theory of color vision that suggests the human eye has three types of cones, each sensitive to different wavelengths of light (red, green, and blue). These cones work together to create our perception of color.

Opponent Process Theory:

This theory suggests that our perception of color is based on opposing pairs - red vs. green, blue vs. yellow, and black vs. white.

Cones:

Photoreceptor cells in the retina that are responsible for detecting color and fine details.

Wavelengths: The distance between two peaks or troughs of a wave; in terms of vision, different wavelengths correspond to different colors.
