The approach of the Web accessibility is necessary for all the people to be able to use websites. As the visual elements are very important factors in the website, in our previous study, the visibility of young adults, the elderly and dichromatic vision was evaluated using the simulation filters. In this report, we made a model of discriminant analysis using the results of the paired comparison for predicting the website visibility. As the results, the difference between young adults and the elderly simulation was not confirmed at using the simulation filters. However, apart from the above, at dichromatic vision simulation, the visibility was very low when G-value of RGB is 66 and R-value is small. Therefore, when the character colors in this RGB region are used, the website visibility has to be considered carefully.
