There is a test on which people check their ability to see color.
http://www.xrite.com/online-color-test-challenge It's not hard but it's very telling when it comes to this sort of debate. The lower your score the better. The last time I did it (a few weeks ago) I scored 7.
It's really fascinating learning color theory and understanding how different people perceive color. When I was majoring in Interior Design, that was one of the things we discussed, and how some colors that look great to one person will look awful to another, and how lighting alters color. It's really cool, and definitely a mindfuck.
