I have a 2000 and the bottom color looks the same. I was told that the paint on CC's for that year Sikkens
https://www.sikkens.com/. The lower color is a code of 316G4 which represents the chip number in the Sikkens catalogue. It is the page number and code. Sikkens paint is very expensive.
I had a local auto paint vendor scan a cover off the fuel fill and mixed a Wanda urethane (
https://wandarefinish.us/). It matched well. You will also need a clear coat to match the paint.
If the door finish is bubbling, PM me for further info.
