Abstract
Analysis using the LUTCHI data set and a new psychophysical colour appearance data set, CII-Kwak, showed that current colour appearance models fail to predict several critical colour appearance phenomena. In this paper, a new colour appearance model, Kwak03, is introduced, which has been derived to overcome the shortcomings found in the previous models. Kwak03 follows the basic structure of CIECAM02 but makes several major changes, such as the formation of the achromatic signal and dynamic response function. It is shown that Kwak03 outperforms all previous colour appearance models, especially in predicting changes in colour appearance with different viewing parameters.
