摘要

A psychophysical experiment under constant stimuli is conducted on a CRT display to measure the visual suprathreshold color differences for five color centers recommended by CIE under the same five background colors.The performances of four CIELAB-based,three CIECAM02-based,and two OSA-UCS-based formulas are tested.Detailed analysis results indicate the existence of chromatic crispening effect.CIEDE2000 performs best for the gray center and gray background,whereas CAM02-LCD and CAM02-UCS have the best performance for non-neutral backgrounds.CAM02-LCD significantly outperforms all other formulas for all color centers under all background colors.
