Abstract : This report discusses color-appearance problems arising in self-luminous displays (SLDs), with special emphasis on computer-generated displays. Since no color appearance system designed for SLDs is yet available, many users apply one of the color appearance systems that have been developed for use with reflective materials. These systems can be helpful for managing color appearance in SLDs, especially when the display is intended to simulate a natural scene containing reflective objects and surfaces. The report provides guidelines for simulating samples from four such systems (Munsell, NCS, DIN, and OSA) on SLDs, pointing out the essential role played by context and background in determining color appearance. Figures and graphs are used to illustrate the differences between reflective samples and SLDs with respect to their gamuts of realizable colors. Attention is drawn to problems inherent in the concepts of brightness, lightness, colorfulness, and grayness since these problems have special implications for SLDs. The report suggests different uses for which each of the four color appearance systems is particularly well suited.
