Lower frequency spectrum, I'd venture to say. We can't see infra-red, and we can't see ultraviolet, and magenta-red is moving to the extremes of our visual perception.

Actually, humans can see ultraviolet, but it's filtered out by the lens in the human eye that focuses light. Some people are born without that lens, or some people lose it due to disease or injury, describe ultraviolet light as "blue-white".
Color is incredibly fascinating. It's something that we think we kind of understand, but really have very, very little understanding about, because perception of the signals coming from our eyes is determined by the mind which we don't understand.
