Well one of the things you might consider is a decal of some sort?

A trim stripe or something along those lines?

Or if it's Monokote, IIRC there are smaller rolls available, i.e. 5"x36" and the Empire has those. Not sure about the UltraCote since I just bought the full rolls when I needed some to color match my gap seals.

Or if someone in your club or circle of friends might have the color you want.
