Also Georgia's looks like it has a butt on it. :P

Some of those are so cheap. Alaska has such a beautiful sign, then others like California are just a regular tin road sign.

From what I understand most colorblind people who drive say they can still tell a green from a red light. They don't just see black and white, but all the different shades in between. Even then this would only be useful at night, in theory. However it seems unlikely that one could really tell a glowing triangle from a glowing circle from a distance at night. All that said and how few drivers would be affected this seems a bit silly.
