How common is color blindness? I'm not saying it shouldn't be a consideration, I've just heard it mentioned a lot and I'm curious if it's much more common than I had originally though (low single-digit percentages, higher among males)?
What I've heard fairly often is the percentage ranges from 8-12% of males.
Of course, some colorblind people also use IE6, so there's overlap there, but is still rather code for colorblind people than IE6.
EDIT: found this, but haven't tried yet: https://chrome.google.com/webstore/detail/chrome-daltonize/e...
3%+ of total population sounds like enough people to pressure at least one video card vendor to offer equivalent remapping. So why is this a web design problem?
(And what part of "design" doesn't include usability, anyway?)
It seems quite common actually - I've met quite a few people that suffer it (not that this is anything other than anecdotal info, but...)
