See How Color Blind You Are In This Color Test
Maybe you know a thing or two about '50 Shades of Grey', but how well are you at choosing colors? You've seen those paint cards that all have the same color, but pair them next to each other and they're ever-so-slightly different. Take this test to see how well you are at your colors. The answer may shock you!
I scored an 8 which is pretty good. I cheated, however. I looked without my glasses on which made the colors blur together so I could see them better, but even still I didn't get a perfect score which tells you how hard this challenge is.
