Pantone is a system for making up well-defined colors in a printing process. RGB is not applicable there. CMYK is somewhat closer, but it doesn't do the job either -- there are plenty of Pantone colors that can't be created by process color (CMYK). Pantone is proprietary, perhaps, in a sense. But it's an industry standard known by everyone in the printing industry world wide. If you want to tell a printer about a color, that's how you do it. I suspect it predates RGB color and computer graphics, though I'm not sure about that. paul
