optillusions:

Though not strictly an optical illusion, the Isihara Color Blindness test illustrates the variability of human perception. The numeral “82” here is clearly visible to viewers with normal color vision.

Having perfect colour vision, I can see it. 

I love these things. (well. that feel of superiority I get when people complain they can’t see anything)
