Abstract
In this paper, firstly, we described a paired comparison test of foreground (character) and background colors. The color sets were selected from achromatic colors of the Web Safe Color, which is a de facto standard for the HTML color representation. Secondly, we showed a SOM (Self-Organizing Maps) analysis to estimate different color sets for visibility of same users. Since a user profiling is required beforehand for every user, we solved this problem with SOM. Finally, we proposed a Web browsing method with an automatic color correction (palette changing) for personal user's visibility. We applied the result of the test and analysis to our method, and we implemented a Palette Changing System for evaluating of usability as CGI (Common Gateway Interface) software on a HTTP server of the Internet. It was suggested that our method is useful for automatic color correction of Web browsing and is available for improving visibility and individual personal usability.
