Web accessibility: Summize has options for color-deficient people

July 26, 2007

Indirectly related to the Shopping sphere: I recently browsed Summize, an aggregator of product reviews that I covered in March, to see latest features. Unfortunately, they didn’t really improve their search engine since my last visit (that was my main critic at this time); but they added a feature that I found really innovative for this kind of mainstream service: the capacity for color-deficient people to switch to black&white display. As explained on Summize blog:

“In color blind mode, snips are rendered from black-to-white rather than red-to-green. Grayscale snips address all varieties of color blindness (even true color blindness of the rare monochromat)”

Really nice example of web accessibility:

You talked about people with color deficits yet on this page, there are instances of low contrast that are very difficult for those people. The quotation (blockquote, I assume) has a contrast ration of 1.6 and the area where you say "My Job" has a ratio of 2.1. WCAG 2.0 currently has a requirement of a contrast ratio of at least 5 at level AA (think priority 2). There is no requirement at level A.

Oh yes, and I was interested in your CAPTCHA - but I couldn't get the audio version to work. Probaby user error!

Hi Jim, yes, you're perfectly right... It's sometimes easy to recognize good work, and sometimes difficult to apply the same rules for yourself :) Will try to change the blockquote color in the next days.

Thanks for the notes regarding the "theory" :) really interesting.

By the way, Jim, your site is really interesting! Lot of valuable info on it, when I can learn more about accessibility :)
