Question

Quizplus · Accepted Answer

The fact that some cones in the retina respond primarily to red light, while others respond primarily to blue light, supports the trichromatic theory of color vision. This theory proposes that color vision results from the activity of three types of cones in the retina that are most sensitive to different wavelengths of light (red, green, and blue). These cones work together to enable us to perceive the full spectrum of colors.
