Couldn't you also describe color kind of objectively as a certain wavelength? I guess purple has no wavelength associated to it.
Anyway, in the end the human eye of a non-colorblind person (sorry) decides which color a surface is. Two surfaces should be considered the same color if they stimulate the color receptors in the same way.
Pantone colors, CMYK colors and RBG colors still just stimulate color receptors in the eyes, so I still feel like they should be translatable.
There are a finite amount of RGB colors, of course, so we'd have to talk about arbitrary precision real number RGB, not just 24 bit. And another issue I can see, is that RBG can look different depending on the screen. There are calibrated screens, though – I think that means that someone has defined how FF0000 has to look like exactly.
This is not a correction, more a question. How can CMYK, RGB and Pantone be incompatible if the final arbiter is the same human eye?
