gamut The range of colors an individual color device is capable of reproducing. Each
device capable of reproducing color has a unique gamut determined by age, frequency
of use, and other elements such as inks and paper. See also
device characterization ,
device dependent , gamut mapping , ICC profile .
gamut mapping The process of identifying colors outside a device’s gamut and then
calculating the nearest color within its gamut. Gamut mapping is used when receiving
color information from another color space. See also
color space , gamut .
grayscale An image whose only colors are shades of gray. Usually grayscale images
have smaller file sizes because less information is required to display a gray pixel, in
which the red, green, and blue pixel elements all emit an equal intensity. See also
