I remember reading somewhere how color perception is partly cultural, you
learn the "boundaries" when a small child.  Specifically, I remember 
reading how a Korean person would identify a green traffic light as blue,
because the boundary between green and blue are at a longer wavelength.
Westerners see it as green tinged toward blue (supposedly to help color
blind people identify it better).

Unfortunately, I don't have a reference for whatever I read, or any Korean 
people around.
