  Color-weak persons, who in Japan represent approximately 5% of male and 0.2% of female population, may not be able to discriminate among colors of tablets. Thus using color-weak simulation by VariantorTM we evaluated the effects of background colors (light, medium, and dark gray, purple, blue, and blue green) on discrimination among yellow, yellow red, red, and mixed group tablets by our established method. In addition, the influence of white 10-mm ruled squares on background sheets was examined, and the change in color of the tablets and background sheets through the simulation measured. Variance analysis of the data obtained from 42 volunteers demonstrated that with color-weak vision, the best discrimination among yellow, yellow red, or mixed group tablets was achieved on a dark gray background sheet, and a blue background sheet was useful to discriminate among each tablet group in all colors including red. These results were compared with those previously obtained with healthy and cataractous vision, suggesting that gap in color hue and chroma as well as value between background sheets and tablets affects discrimination with color-weak vision. The observed positive effects of white ruled squares, in contrast to those observed on healthy and cataractous vision, demonstrate that a background sheet arranged by two colors allows color-weak persons to discriminate among all sets of tablets in a sharp and feasible manner.<br>
