Color blindness testing

I was reading though my week old RSS feed data (collected whilst of "vacation") and came across a post on the Unofficial Apple Blog about Color Oracle which allows the simulation of various forms of color blindness for visual testing. Not only is it available on the Mac, but Windows and Linux too. Free to boot.

That's neat. Another method to test for this is to take a screen shot and change it to gray scale. This ensures your contrast ratios are high enough as well.

In windows (Vista at least), there's an option in the 'Ease of Access' menu to up the contrast for color blind people. Just thought I'd throw that in.

This Accessibility Color Wheel has been mentioned on these forums before.

It is my opinion that user accessibility is not something the majority of us really take into consideration during design, despite the fact that it a legal requirement in many countries.

I always test by printing the web-page on a black and white laser printer. If it is still good readably it's ok. And another benifed of printing it, is that you see how the page comes out of the printer (or is it printable).

color blindness test. It doesn't mean you just see black and white. If you are a male, your chances of having a green or red disability are 1 in 20. Go ahead, take a test.

This is something I I didn't consider at all in all my designs so far. So thinking back at what I've done over the years, I think I caused much problems to those who don't see as well as we do. :( This sucks!
