Color deficiency is ordinarily caused by unfunctionality of one cone type in three cone types on human retina by a genetic reason. Ordinary color deficient people, protanopes and deuteranopes, cannot discriminate certain combinations of colors, especially certain combinations of red and green. This problem can be minimized by using suitable color combinations on color presentation like sign, called as color universal design. However, it is difficult for color normal people to use suitable colors for the color universal design. Thus, we have developed the optical functional-filter, which can simulate the difficulty of color discrimination on protanopes and deuteranopes, as a tool of the color universal design. The filter is quantitatively enough accurate as a checking tool for color discrimination of color deficients. Furthermore, by psychophysical experiments, we have investigated how extent this filter is effective as the simulation of color appearance of color deficients for color normal people. With the investigation of color appearance of color deficients, we found that the filter is enough effective and in a certain extent, it is reasonable as the simulation of color appearance.
