Colour contrast for dyslexics

Mel Pedley‘s second article in her series on designing for dyslexics is now available to read over at Accessites. It’s another excellent read that provides some anecdotal evidence towards adopting Hewlett Packard’s colour difference threshold over that suggested by checkpoint 2.2 of the Web Content Accessibility Guidelines (WCAG) 1.0. To support testing against Hewlett Packard’s algorithm, Mel has created an alternative colour contrast analyser and kindly asks for any feedback on it.
