Color vision is an ability of animals to perceive differences between light composed of different wavelengths (i.e., different spectral power distributions) independently of light perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of photoreceptors by light entering.

    Colour vision deficiencies can be either acquired or inherited/congenital. A congenital disorder, or congenital disease, is a condition existing at birth, and often before birth.

This fairly common condition often goes undiagnosed, because patients do not realize they aren’t seeing colors like other people do. yet testing for color blindness is simple and doesn’t even require a trip to the doctor. A special property of the cone system is color vision. Perceiving color allows humans (and many other animals) to discriminate objects on the basis of the distribution of the wavelengths of light that they reflect to the eye.

While differences in luminance are often sufficient to distinguish objects, color adds another perceptual dimension that is especially useful when differences in Author: Dale Purves, George J Augustine, David Fitzpatrick, Lawrence C Katz, Anthony-Samuel LaMantia, James.
