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)

I was going to post this image (credit) and laugh about it but in fact I can’t see anything here. I’m not colour blind — I went off and did a six plate test to check and I’m really not… but I can’t see anything here.

Am I being trolled or am I blinder than I thought?

I see an 87. :/

I can’t see anything.

Herp derp. 30 second in an image editing program checking the RGB values of the circles will tell you that this is bullshit.

Also, if you believe the internet to tell you you’re colourblind…well….die in a fire.
