Aside from looking in hidden places for the original color, try this:
- Open the trunk and pull up the spare tire cover. There is a large loop inside the lid that allows you to attach it to a hook on the inside of the trunk lid.
- On the left side of the spare tire well, or somewhere, there should be a Service Parts Identification sticker.
- I found my paint code (30U - silver) on the bottom line, third code in from the left.
- Paint codes are here under paint:
