This is just a test for fun.
You click on the blocks and rearrange them on the colour spectrum.
You get a score on a scale between 0 and 99, with 0 being Perfect Color Acuity and 99 being Low Color Acuity.
I actually got zero which is quite a surprise. The lower the score the better your "colour vision".
I do admit it's a bit hard and you need to squint a little.. but try it out and tell me how well you did!! ^_^
