As far as I can see, you are helping my point (perhaps that is what you intended): suppose that you saw those subtle transitions in, say, the wood of a kitchen table, and decided to make a printing that portrayed them. Suppose, as well, that your art colleagues have less color discrimination than you, and didn't see those transitions in wood color. They would also fails to see them in your printed portrait of them. So, you would have two entities, wood and print, which would match each other in color both for you and your colleagues. It's just that the colors thus matched would be beautiful and subtle for you, boring for them.
