His theory was that color—in abstraction from the object that is colored—may start mattering to people only once they become exposed to artificial paints and dyes. The appreciation of color as a property independent of a particular material may thus have developed only hand in hand with the capacity to manipulate colors artificially. And that capacity, he notes, barely existed in Homer’s day: the art of dyeing was only in its infancy, cultivation of flowers was not practiced, and almost all the brightly colored objects that we take for granted were entirely absent.
