Violet is in the rainbow. Like magenta, it is a combination of red and blue (#8F00FF). This is because there's a second hump in the frequency sensitivity of the red receptor. See: http://en.wikipedia.org/wiki/CIE_1931_color_space#Color_matching_functions http://en.wikipedia.org/wiki/CIE_1931_color_space#Color_matc... So there is a "between red and blue" in the spectrum. Just no place where there's more red than blue.

It's not in the rainbow as in the diagram you link to ("CIE 1931 color space chromaticity diagram"). The diagram has the R G B "in 2 dimensions" and the values between and the rainbow has it as R G B "in one dimension" and the values between. Edit: under "it" I wrote about magenta, as the main article writes too. The "drawings" are about the appearance of magenta. I see you talk about violet. Yes it is an interesting observation about how we see the colors.

  What happens if your eye sees pure 400nm light? There is some stimulation of the "red" receptor and more stimulation of the "blue" receptor. I think the fact that we DO see violet in the spectrum is more interesting than the fact that we DON'T see magenta.
