Color is not claimed as a feature of the mark.
The mark consists of a design split into 4 equal squares (going left to right on top and left to right on bottom). There is one Helvetica letter per each square: "P", "A", "R", "T", in the same order as the aforementioned squares. "P" is in the top left square, "A" is in the top right square, "R" is in the bottom left square, and "T" is in the bottom right square.
