Pantone uses coded colors (e.g. things like "#106U Bright Yellow"), with each having RGB and CMYK values, physical ink-mixing proportions for custom printing, paint standards, etc. From what I understand it's pretty popular with corporate marketing because it takes the hassle out of getting extremely consistent colors across different physical and digital media.
