what paint to use on the cup area of a door handle?

Does anyone know what type and color of paint to use on the cup of an exterior Challenger door handle? My handles are in great shape just need new paint.

I'm going to try this out on mine.

I've seen using it on other stuff and it duplicates the metallic flakes really well like just like inside the door handles. It might not be the perfect match like OEM but I think it could be a close match.

After spraying it on, I plan to shoot a light coat of Krylon matte clear UV resistant.
