Apparently there are some people -- called tetrachromats -- who can see color in four dimensions. They have extra sets of cones in their retinas containing a different photopigment. So, the dimensions of color appear to be an artifact of our visual systems, and not inherent in the colors themselves which are linear (one-dimensional) in frequency. http://en.wikipedia.org/wiki/Tetrachromacy -- http://mail.python.org/mailman/listinfo/python-list
