Being Aware of Colour Blindness

[Sue Mackay]

I am a croquet player and run two croquet websites. A lot of male players are colour blind and have trouble telling the various balls apart, and a recent discussion on our croquet forum contained this interesting link for testing how your website looks to colour blind people (there are more of them than you might think). I was amazed at how my sites looked, though relieved that at least the text was still legible when the colours changed.

There are many different types of colour blindness (protanopia, deutanopia etc), depending on which detectors are non-functioning. See the link below (or do a google search on colour blind tests)

The page above has a link to the Isihara test, which has been the standard one used - many of you will probably remember it from school.

This is the link that is useful for web page designers.

It will show you what a web page looks like to people with all the major colour deficiencies.

That's a very interesting thought Sue, and one I hadn't thought of. Thank you.

Thanks for that Sue, glad to say my pages pass the test on most filters.

Thanks, Sue!

Interesting to find out at this late date that I'm color blind! And I'd thought that people who use some of the strange background and text color combos on web sites were just plain nuts. :)
