CIE L*U*V* Color Space

The 1978 CIE L*U*V* color space is preferred for computer monitors because it more accurately represents human color perception. Distance between colors in CIELUV approximate the differences disguished by the human visual system. Therefore, CIELUV color space is preferred for determining optimum color sets for use in coding information on displays.
1978 CIE L*U*V*

CIE diagrams are used to determine the "gamut" or range of colors that can be displayed by a particular monitor by plotting the red, green, and blue primaries and joining them with straight lines to form a triangle. All colors that can be produced by the display lie within the triangle. This should be the first step in choosing colors to use on a display. The next is to choose colors that lie at least 100 color units apart. These differences can be computed after conversion into 1978 CIE L*U*V* space and applying appropriate equations.

Note: Inclusion of the necessary calculations is beyond the current scope of this course. The student is referred to Effective Color Displays by David Travis (1991) or Color in Electronic Displays edited by Widdel and Post (1992).
