Most I see aren't really ugly, but just weird looking. Some look white when you first see them, but something about them looks off. Then you find out they're mixed and you're ooohh....that's why you look weird.

The only non-weird looking mixed are mestizo's. Since they're been breeding out weird features for two or three centuries they look normal.

Obviously, mutatto's are the most hideous of the racially mixed, almost uglier than full blooded negro's.
