Abstract
The rapid dissemination of the World Wide Web raises the issue of the Web accessibility, and one of the important things is the combination of a foreground color and a background color. In our previous study, the visibility of web-safe colors on the white background was examined, and the blue used for unvisited standard link color was found high visibility in wide range of ages. Since the usage of the blue and an underline are recommended as link, in this study, we examined high-visibility background colors to the unvisited standard link color, i.e. blue. One hundred and twenty four background colors to the blue were examined using pair comparison method. As the results, when the contrast between standard link color and background color was 1.37 or more, we obtained the high scores from the colors. This indicates that these colors show the high visibility and are useful as background colors.
