The complexities of colour

I've just been trying to explain the Pantone referencing system to Mr CK and hopped over to their website, where they are proudly announcing 175 new colours, bringing their total up to 2100 colours.  Part of me is a bit concerned that they have somehow managed to commodify colour; another bit deeply in awe.  But I was fascinated by  this video explaining a little bit about what they do.
