A new color universal design method with two steps for color combination has been proposed. The first step is to make a color combination with colors dichromats can discriminate. Next step is to change each of the color combination to other which dichromats cannot discriminate, respectively. However, because this method still has some critical problems, it is not made practicable in color universal design. In this study, we clarified these critical problems and proposed solutions to resolve them. In addition, we made a set of color samples according to the solution method. Hereby, we show an approach for putting the new color universal design method into practical use.
