A) all three types of cones are equally active.
B) both the red-green and the yellow-blue systems are at their neutral point.
C) a cone produces impulses at a high, steady rate.
D) cones fire impulses at the same rate as rods.
Trichromatic Theory
A theory of color vision that proposes that the eye has three types of receptors with differing sensitivities to different light wavelengths.
Perceive White
The process by which the visual system interprets a spectrum of light that reflects off surfaces without significant absorption, resulting in the perception of white color.
Three Types Of Cones
Refers to the three kinds of cone cells in the human eye that are sensitive to different wavelengths of light, enabling color vision: red, green, and blue cones.
