Ah, the things you stumble across when it is after midnight and you can't sleep. I took a color IQ test. Believe it or not, I got a zero, which means I have perfect color vision. Ha, all those art classes did pay off. Okay, maybe they didn't actually pay off, but at least I did pay attention.
Actually, I took it twice and the second time I scored a four, so I guess my vision is already deteriorating. Oh no!
Try it, you'll like it.
