Robbie, For a foreground/background colour pair to show good contrast, they should pass tests for colour difference and brightness. The W3C provides two algorithms for working these out. Essentially, a colour pair must return a score of 500 or higher for colour difference and a score of 125 or higher for brightness. HP propose a slightly more lenient score of 400 for colour brightness, which is perfectly acceptable. There are several online tools you can use to test two colours, providing you have the hex colour codes. There's one on my site: http://www.tink.co.uk/content/colour_checker.php Regards, Léonie. -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Robbie Miller Sent: 05 October 2007 15:01 To: Blind Programming Subject: web accessibility testing Hello Listers, I've been asked to do an accessibility - section 508 evaluation of a web site. My question is, how can I test a page to see if it: 1.) "Remain Independent of Color" and 2.) "Stay Independent of Style Sheets"? Are there any tools I can use to do this? Any help on this would be appreciated. Also, if there are any resources on web accessibility testing, please let me know. Thank you.
