Colorimetric match between different color reproduction medias does not ensure visual match. One of the reasons that mediate this discrepancy is the variation in color matching functions (CMFs). We have measured CMFs of observers in color matching experiments. Previously, we conducted metameric matching experiment to evaluate the CMFs (Hatakeyama et al., 2016). In the results, the validity of the CMFs for the colors of the long and meddle wavelength region was confirmed, while some residual color differences were observed for the colors of the short wavelength region. Although nonlinearity in the region has been reported to depend on the saturation conditions when measuring the CMFs, it has not yet confirmed whether it affects on metamerism. We repeated the color matching experiment with less saturated stimuli, and examined the effects of saturation. The results showed that the residual color differences were also observed, suggesting that the nonlinearity of CMFs does not simply depend only on saturation.
