For the Audi R8 Side Blade, start with the make-specific code guidance: Audi paint color codes are printed on a paper color id tag, often found around the spare tire area; some Audis also have a metal plate on the driver door jamb. The paper tag can fall off and disappear over time, leaving codes unavailable. Codes can include two parts, e.g., LY9H and P1; LY9H often corresponds to Polar White Clearcoat, and P1 can be used for the same white on some models. Older Audi models can be hard to identify by code; custom matching may be required. If the label is missing, ask a dealer parts department for a VIN lookup before ordering paint.
