Research Abstract

I precisely measured the brightness, chromaticity, and spectral radiance for 216 web-safe colors, and accumulated the measurements into a database. By using this database, it became possible to calculate various types of luminous contrast between web-safe colors. And, as a result of evaluating WCAG2. 0 based on age-related spectral efficacy, considering the effect of aging, WCAG2. 0 success criteria are mostly suitable for web-safe colors, while we must be careful to use the colors on the blue region due to the decrease of the luminance contrast ratio.
