Development and Application of Color Appearance Phenomenon and Color Appearance Model

In the study on chromaticity of human eye color vision rules, the qualitative and quantitative expression of color can not be separated from the three color perception experience elements: illumination body, color source and observer. The chromaticity stage is established on the basis of color matching and chromatic aberration stage, namely the third stage of the development of CIE chromaticity. Because the traditional CIE LAB color space hue lacks visual uniformity, chromatic aberration calculation is only suitable for the color difference under specific observation conditions. In order to solve the influence of color adaptation, color contrast and other related color appearance model phenomenon, and accurately predict the morphological parameters of color under different light sources, lighting levels, observation background and media, etc., the color appearance model was proposed and continuously developed, which has important application value for the research on the replication and transmission of cross-media color information.
