If you hadn't guessed from

If you hadn’t guessed from a brief visit to his site, Cal is colourblind. Hey – what can be said – I have no sense of smell, he doesn’t know how to co-ordinate. We all have our crosses to bear. Unfortunately I’m not as absurdly talented as Cal is, so I can’t do something tremendously, world-changingly useful – like make a site which allows you to test various colour combinations to see how accessible your site will be. [Addendum: For those who have asked, Cal is a good friend of mine, and I was merely joking about the colour-schemes at his site. In fact even a cursory glance would demonstrate that the colour schemes are great. And that there are lots of them.]
