A series of psychophysical assessment data for investigating the color appearance in LED panel influenced by the level of ambient illuminant were accumulated. The perceptual attributes of test color patches, displayed in LED panel under bright, average and dark environments respectively, were evaluated. The experimental results indicate that the lightness and brightness are larger when viewing in dark and the lightness and brightness are smaller when viewing in bright sunny day. The visual data were used to compare with the corresponding data predicted by CIECAM02, and a modified CIECAM02 color appearance model with condition parameters correction is developed. A paired comparison experiment is carried out to verify the perceptual attributes predicted by the proposed CIECAM02 have good performance in various levels of illuminant.
