An intuitive and device-independent method of generating color atlases for electronic displays

Abstract

We propose a HCL mix color system that can describe accurate colors on different electronic displays. Algorithms for computing the threshold values of chroma and lightness are devised so that the HCL mix color system can create the 3D color gamut of a display. We propose an intuitive and device-independent method of generating a color atlas in the HCL mix color system. Users can find the desired colors in the 3D color gamut by using perceptually descriptive items for hue names, color tones, and lightness levels. The system is helpful for color schemes of computer-designed products. Simulation results of generated color atlases are given to show the feasibility and effectiveness of the method.
