In order to obtain the proper degree of color enhancement for anomalous color vision, difference of perceived saturation between two chromatic stimuli was measured. Before the saturation experiment, brightness matching was done using the test stimuli. Saturation differences are evaluated using a brightness difference for red, yellow, green, and blue stimulus sequences. Results of one weak deuteranomalous observer showed that perceived difference of saturation of the red and green stimulus pairs is smaller than those of normal observers, while no significant difference was obtained for yellow and blue stimulus pairs.
