The present disclosure relates generally to the modification of color lookup tables for rendering color images on devices.
A color image may be rendered on a device such as a display or a printer. Differences in hardware and software of devices, differences in viewing environment, and differences in human observers of a particular image may cause the image to appear differently when rendered on different devices. For example, hair color in a portrait may appear “correct” when observed on a computer display, but may not be “correct” when printed and observed in fluorescent lighting. A color lookup table (CLUT) is used to translate color between a device and a standard color space. By making changes to a CLUT, the preferences of an observer may be consistently applied to images rendered on a particular device.
