Colour Test

Apparently 1 in 255 women and 1 in 12 men have some form of colour sight deficiency. Well yes, we know that red-green colour blindness is a largely male inherited trait. But of course it's more complicated than that.



Thanks to Ed Yong over at Discover Blogs I've just found this rather strange, and quite tricky colour acuity test. It's not a test for colour blindness as such but more about how well you differentiate colours.

Try it. It'll take about 5 minutes.

Oh and I scored 7, which seems pretty good (0 is best; 100 is worst).

There's a lot more on colour vision and colour blindness on Wikipedia.
