Color blind approach is the hypothesis that, to reduce prejudice, people should be encouraged to categorize other people as individual persons rather than as members of groups

Color blindness is defined as a total inability to perceive colors.

Color constancy refers to the ability to recognize the color of an object despite changes in lighting. It is the effect in which the perception of an object’s hue remains constant even when the wavelength distribution of the illumination is changed. Approximate color constancy means that our perception of hue usually changes a little when the illumination changes, though not as much as we might expect from the change in the wavelengths of light reaching the eye.

Color deficiency is a condition affecting people who see fewer colors than people with normal color vision and need to mix fewer wavelengths to match any other wavelength in the spectrum. Color deficiency is sometimes incorrectly called Color blindness.

Color vision deficiency refers to the inability to perceive color differences as most other people do

Color weakness refers to an inability to distinguish some colors.
Color-blind refers to a condition in which a person perceives no chromatic color. This can be caused by absent or malfunctioning cone receptors or by cortical damage.

Color-matching experiment is a procedure in which observers are asked to match the color in one field by mixing two (2) or more lights in another field.
