Two psychological experiments were camed out to evaluate visual comfort to a colored environment. One measured the number of colors contained in the colored image of a natural scene briefly presented on a CRT display by asking the subject to report all the perceived colors based on the categorical color naming technique. The other measured the optimum rate of chromaticness at which the subject felt the most comfortable impression against the scene when the chromaticness of every point of the colored image was gradually changed at the same proportional rate to the original chromaticness of each point. The results showed that the direct estimation of comfort to an image was in good negative correlation with the number of categorical colors, and in good positive correlation with the optimum rube of chromaticness. It was concluded that the both the number of categorical colors and the rate of chromaticness employed here were useful measures for evaluating visual comfort to a colored environment.
