Be careful though, if you want to visually distinguish between colours with 
your eye (or anything else that uses RGB) you only have 3 degrees of 
freedom.  Of course you could use spectrometers and then you could even make 
a load of "different" colours that look the same to eyes and 
cameras/scanners, but actually have different spectra.  That would be pretty 
cool.
