Oh, and about red and blue...

I was at a magic show once in college where the magician was more or less giving a lecture on not being fooled by things that seemed "magical." (I went to a Christian college.) The magician wrote something on a piece of cardboard, then had a random male student stand up. He asked the student to tell him what his favorite color was, and the student said blue. The magician turned his card around and written on it was the word, "blue."

He then went on to explain that if you ask men what their favorite color is, something like 80% or more will say that it is blue. So, writing blue was simply playing the odds. Someone asked him what he would do if a man chose another color, and he said he had a funny joke ready to tell in order to make it seem like his mistake was intentional.

Something that may play into this male color choice is the fact that the majority of people who are color blind are men. The most common color blindness is red-green. So, if you can't see a color properly and struggle with its identification, you're not likely to choose it as your favorite.

I knew a guy who was red-green color blind and I asked him what it was like. He told me that in bright light he could tell the difference, but if it was dim or shadowy, both colors looked the same to him, just perhaps shaded a bit darker or lighter than the other. I then asked him about red and green traffic lights. He said he went by which light was on or off, rather than by the color.
