Full Idea
I cannot agree that a description of a patch of colour would be complete without the statement that it is beautiful (if that is so); for its beauty might be for some purposes the most important fact about it.

A Reaction
'Important' to whom. To me the most important fact about my pen might be that it is mine, but that doesn't seem to be a feature of an intrinsic description of the pen. If beauty is a relational quality, Ross's point is undermined.
