You are going to be very hard pushed to find a decent pair of any pre-facelift rear wings that aren't at least partially rusted. So getting them in your colour is going to be more difficult still.
I have a pair totally rust free but in Montreal Blue. If you are getting the car resprayed it shouldn't matter. I would prioritise the fact they are rust free over colour. I also have the matching rear bumper cover which you can have for free if you want the wings.
The sills were also rust free (well a little bit of surface on the inside). But they are also very hard to find, sold quickly and will be reappearing soon on another forum members M.
PM me if interested.
