Can you replace the black plug on the rear bumper?

Sorry if this is covered elsewhere, but I don't know what to call it so my search came up empty.

I have a 2010 white roadster. Under the rear bumper there is a 4"x4" black cover plate of some kind. I have shown this car to my family and friends and I have been asked 4,278 times if there is a trailer hitch there under the cover.

Why not paint that silly thing white? Plus the actual tow point is right above that cover. Its madness....

I think I saw on a photo where someone had replaced this with another center brake light.

I don't want to try and paint this because I will never match the pearl white. Any other options? Can you buy a colored cover? Is it for a brake light in another country? Suggestions?
