I found this article by a colo[u]r blind web designer (via digg) quite interesting… at the bottom of the article he links to a bunch of tests for colour blindness.

I’ve always had a bit of difficulty with these - but I was just assuming it was just a focus issue. The final image on page 1 was the thing that convinced me that there might be a slight insensitivity in the red-green area.

My father is red-green colourblind, so I guess it shouldn’t be that big of a suprise.

I can see all the colours quite fine (afaik), in normal circumstances - and I have no trouble with a RGB colour pallete - so I’m guessing it’s just a very slight insensitivity.

Edit: Well… maybe not… I can see them fine on my LCD panel at home, it’s probably just the screwy work laptop screen…
