Paint colour for backing plates ?

For me I'm just going to go with clean. I don't want to get dirty on it or anything like that. But knowing that my car is not going to spend its time rotating above mirrors then actually driving it a little bit on the street in a little bit on the Dragstrip I'm not so worried about how detailed my brake dust catchers are. I think they're so hidden just as long as they're clean they'll be just fine. Unless you are like daily driver? And are back East with salt roads and trying to keep them from rusting?
Not a daily driver, summer weekends only & shows so no worry about salt. It pretty much only rains where I live anyway. I would like the original look or close to it.
