I have it, though only the red/blue kind, but it's still a bummer. Like sometimes, I can't describe something to someone because I don't know what color it is. I seriously have no name for what I'm seeing. That's about the worst part of it, so I feel bad for people who have it worse, because I can imagine it.
My dad has red-and-green colorblindness, but I don't. He has a little trouble seeing the traffic lights, but luckily he has memorized the positions of them. If they were ever to be changed, he'd be completely thrown off.
