Definitions:

Trichromatic Theory

A theory that explains how the human eye sees color by the presence of three types of cones sensitive to different wavelengths of light: short (blue), medium (green), and long (red).

Color Vision

The ability of the eye to distinguish different wavelengths of light, enabling the perception of various colors.

Colorblindness

A genetic or acquired inability to see color or differentiate colors, affecting the perception of hues.

Proprioceptive Feedback

A type of sensory information that provides input on the position and movement of one's body parts, critical for coordinating movements and maintaining posture.
