One of the projects within H.A.I.K.U. which was being conducted as time and research assistants were available, is an automated tool to check colours on webpages to ensure they meet some profile (e.g. suitable for red-green colour blind readers or not a problem for people with ADD) and suggest changes to the author of the webpage. Some of the research that went into development of the tools was shared with the W3C's WAI and CAST's Bobby team.
