A person who needs to mix a minimum of three wavelengths to match any other wavelength in the spectrum but mixes these wavelengths in different proportions from a trichromat. A loss of color vision caused by damage to the cortex. Exposure to light in a specific part of the visible spectrum. This adaptation can cause a decrease in sensitivity to light from the area of the spectrum that was presented during adaptation. Color with hue, such as blue, yellow, red, or green. A condition in which a person perceives no chromatic color. This can be caused by absent or malfunctioning cone receptors or by cortical damage. The effect in which the perception of an object"s hue remains constant even when the wavelength distribution of the illumination is changed.
