Colour blindness - a usability guide for commercial applications 7 Mar 2007
TechNewsWorld has published part one of series on colourblindness and its impact on usability. The article concludes that:
"The safest route to legibility in screen and print layouts is to rely on black fonts and white backgrounds. To place blue or green backgrounds behind black fonts decreases the contrast and degrades readability. The use of red or dark green backgrounds also degrades readability, regardless of font color."
Given that approximately one in twenty people have some form of colour blindess, these recommendations are something that all designers should be aware of. Go take a look (and then why not test your own designs using our colour blindness simulator?)
