Musicians have long enjoyed the benefits of a notation system for music. Anyone who has ever taken music lessons remembers what notes on a staff look like. Artists, however, have never had an equivalent way of referencing color. Instead, we’ve had to make do with imprecise words to signify color, and to great confusion: one person’s “ruby” is another’s “carmine”, while for another it’s definitely “burgundy”. But what do these words really mean? Nobody knows for sure, and that’s where the trouble starts.
