Even if you're not the artistic type (I know, there are some of you out there who are reading this), go ahead. Do it.
Just for fun, test the artistic eye within you, and take the hue test.
It's designed to see how good your eyes are at discerning color differences. This test gives you one hundred blocks in four sets, and you have to click and drag the boxes in order to put the colored squares in order. (Once you click on the site, find your country and click on it - I know it works for 'United States' at least!)
The results then let you see what colors you may have trouble seeing (or at least discerning). A score of zero is perfect. I suspect that most of you will score a zero - like me!
