This is a classic colorblind test. Since my mother is colorblind and my dad is a carrier...I am also colorblind. Contrary to popular belief, colorblindness does not mean that we can't see colors. But because people believe this it is hilarious to make them think that we do. Sometimes when I first meet someone I'll tell them that I am colorblind and that my life is like a black and white movie, which is completely rediculous. Once I convinced one of my friends that because I couldn't see normal colors, I couldn't see cars, but that I saw people floating, driving a fake steering wheel. But nontheless, I am colorblind. It's kind of fun. It doesn't affect lifestyle at all or anything, just certain shades aren't visible or hard to distinguish. Also...I can't become a pilot. In this picture, normal vision should see a 15...? I think. But people with colorblindness, such as I, cannot. Granted I can see that there is a number, I just can't make out a definitive number.
