Here's a cool test a friend of mine found. It measures how well you see color. They call it a 'color IQ-test' - though I don't think vision has anything to do with actual intelligence... Or at least not the kind of vision that you use to look at things. I digress...

Either way I don't make any money so I don't care what you do. I guess that's a fault of mine. I'll work on that. I got a 4 on the scale, with 0 being the best score and 99 being the worst. They add some weird auxillary score at the top of the results page which I don't quite understand. I choose to ignore it. Share your 0-99 scores!
