Nowadays web accessibility refers mainly to users with severe disabilities, neglecting colorblind people, i.e., people lacking a chromatic dimension at receptor level. As a consequence, a wrong usage of colors in a web site, in terms of red or green, together with blue or yellow, may result in a loss of information. Color models and color selection strategies proposed so far fail to accurately address such issues. This article describes a module of the VisAwis (VISual Accessibility for Web Interfaces) project that, following a compromise between usability and accessibility, allow color blind people to select distinguishable colors taking into account their specific missing receptor.
