That's a physical constraint of a carbon-based pigment. One could of course
make an ink with different base particles or solubles. (Epson's cyan
pigment ink is, well, cyan in colour.) I was asking from the point of view
of colour management, colour gamut, greyscale and profiling. Assume for the
moment that I can create an ink to any colour I want.
Cheers
