Color video games are often disadvantageous for people with color blindness. Therefore, the game creator often supports them by displaying a color scheme suitable for a color vision type to solve this problem. However, it is difficult to say that the color scheme solves the handicap. Therefore, we aim to develop a mechanism that can control the advantages and disadvantages of people with color vision diversity and normal color vision by combining suitable colors. To examine color combinations that are difficult for people with normal color vision to discriminate and easy for people with color vision diversity we carried out an experiment using a Deuteranope-simulation filter. The results proved that there are color combinations that people with color vision diversity can easily discriminate. This means that the advantages of color vision and disadvantages of color vision diversity can be controlled appropriately by using color combinations.
