ICC profile
An industry standard color profile format developed by the International Color Consortium
(ICC) that describes the color capabilities, including the gamut, of a color device based on the
differences between an ideal and the current device. The ideal is often provided by the
manufacturer as a color reference file. ICC profiles are implemented on Mac OS computers in
ColorSync and on Windows computers in Image Color Matching (ICM). The Color Server
color management system, ColorWise, supports ICC profiles.
