I have a 2020 Kamiq in white. Does anyone know the colour for the rear diffuser. It's a sort of cross between silver and bronze. It has a couple of scratches that I would like to touch up. I've searched online but can't find anything.

I don't think it's a painted part.

On mine (SE-L) only part of it is painted.

It'll need special paint and special primer. TBH nowadays I use a mobile professional when I need all the little dings done. They have the right primers etc and can get exact paint matches.

For other reasons I've tried most of the touch up paint suppliers and none of them ever seem to know the colours from trim and bumpers.
