Evaluation of Color Perception Among Different Aged Observers Based on Color Matching Experiments

In order to study the observer variability of color perception, 53 observers aging from 20 to 79 were organized to match the 17 color stimuli on the monitor. The spectral power distribution of the target and the matched colors were measured and used to evaluate the color difference threshold at different aged group of observers. The results indicated that the mean CIEDE2000 color difference of all the tested observers was 1.07. The experimental data were calculated by CIE1964 color matching function (CMF) and CIEPO06 CMF. Comparison of the two models showed little difference in color difference thresholds for different aged observers.
