What is CIE color?
The Commission International de l’Eclairage or the CIE system defines a color model that provides a standardized mathematical approach for viewing color. It includes viewing and lighting schemes and attempts to describe color the way the human eye perceives it, with-out any color vision defects. That is, if two people are viewing and describing the same color they would identify it with the same numerical value and obtain a visual match. The CIE system uses three values such as XYZ, RGB, or LAB to numerically identify and map out color gamuts of devices or images. The CIE system is universal and is capable of representing the many different types of color spaces. It is being used more in scanning, color separation programs, PostScript imaging environments and color management systems.
