Definitions:

Cones

Cells in the eye's retina called photoreceptors are essential for perceiving colors and operate optimally in well-lit conditions.

Rods

Photoreceptor cells in the retina of the eye that are highly sensitive to light and enable vision in low-light conditions, but do not support color vision.

Cones

Photoreceptor cells in the retina of the eye that are responsible for color vision and function best in relatively bright light.

Color Opponent Processing

A theory in vision science suggesting that the human visual system interprets color by processing signals from cones and rods in an antagonistic manner.
