I won't say that you are incorrect in the usage, as Dupont also called
other colors "Dulux" in their enamel paint line.< When I used the stuff on Peterbuilt trucks 40 years ago Dupont called their lacquer Duco and their enamel Dulux.
Since the tile of the subject is "Proper Names..." it should be noted that the correct spelling is "Peterbilt" (no 'u').
