Optimal color primaries for three- and multiprimary wide gamut displays

Abstract

We present a collection of principles to compare two sets of color primaries for wide gamut displays. A new, algorithmic three-dimensional method to find optimal color primaries both for three-primary and multiprimary displays is described. The method was implemented in a computer program. The resulting optimal color primary sets are discussed. We show that two-dimensional methods to find optimal color primaries by using a chromaticity diagram are inferior to three-dimensional optimization techniques that include luminance information.
