We have tried the visibility prediction in consideration of Web accessibility. In our previous studies, visibility of young adults, the elderly, and dichromat's visibility (Protanope and Deuteranope) has been predicted, respectively. However, it is necessary to group together formula of visibility prediction. In this report, visibility of dichromat's visibility was predicted using transformation of color vision model and linear discriminant function of young adults. As the results, As the results, there was no difference in visibilities between protanope, deuteranope, and observed value. However, when a font color has many red component, the result of deuteranope visibility prediction was a tendency judged low Therefore, it was shown that visibility prediction can be performed using our proposed method.
