Red-green System

The red-green system refers to one of the color vision subsystems in the eye, responsible for detecting wavelengths of light associated with red and green colors, integral to human color vision.

Trichromatic Theory

A theory of color vision positing that the human eye has three types of receptors with different sensitivities to light wavelengths, corresponding to red, green, and blue colors.

Medium-wavelength Cones

Photoreceptor cells in the retina responsible for mediating color vision in moderate to bright light conditions, typically sensitive to wavelengths perceived as green.

Perceive Green

The process of detecting the color green through the visual system, involving specific photoreceptors in the eyes.
