Want to test how well you perceive color? Want to make sure you're not colorblind? You should take this test. Because I'm nosy and want to see how people here score.
I stumbled upon this test while trying to prove to a friend that I'm not a tetrachromat just because I can differentiate between magenta and red. (Un?)Fortunately, I had a perfect score. Doesn't mean I am but that was hilarious. Anyways...
The test took me around 30 minutes and I got a score of 0 (lower is better). My friend took less than 10 minutes.... somehow... and scored 52. So I'm warning you that it's not a quick thing.
