Good commentary on Neilsen's piece here:
I was just wandering what does it mean if in the bottom test you can see both a 5 and a 2.
And the 6 In the top test looks a bit like an 8
sorry for asking a weird question

I don't know for sure, but I'd guess that if you can see the 'right' (i.e. no colour-blindness) answers at all, then the chances are that you are not colour-blind.
