A review on chromatic adaptation transforms and evaluation of the accuracy of CAT02 chromatic adaptation transform for predicting corresponding colors by visual assessment

In this paper, at first, the chromatic adaptation transforms and the proposed methods for preparation of corresponding colors are reviewed. Then, the CIECAT02 CIE chromatic adaptation transform is used to prepare 7 pairs of corresponding color. The results show that the CAT02 model introduces a color difference error about the 4 degree of gray scale in comparison with visual assessments. In the next part, 12 corresponding color pairs from Munsell book of color have been prepared by employing a set of visual assessment test. Evaluating of CAT02 model with the prepared set shows that the performance of CAT02 is dependent on the color hue of the samples and it almost benefits from acceptable performance in the red and purple hues while performs the worst results in the yellow and orange region.
