Summary

This chapter describes methods to optimize the color gamut of three-primary (RGB) and multi-primary displays (those having more than three primary colors, for example, five: cyan and magenta in addition to red, green, and blue). To obtain a large color gamut, the sets of target colors to be covered have to be carefully chosen to be able to render the colors of the most important natural wide-gamut images. Besides the target color set, however, there are several further important factors to be considered including color quantization levels, the number of color primaries, the white point, the issues of virtual primaries and technological constraints, and also the visually acceptable luminance ratio between each primary color and the white point of the display. Examples of optimized multi-primary subpixel architectures are also shown togetherwith the principles of a color image rendering algorithm.
