Silver Ice Metallic (GAN) and Cherry Red Tintcoat (GSK) were dropped; Sterling Gray Metallic (GXD), Harvest Bronze Metallic (GXN) and Radiant Red Tintcoat (GNT) added, for eleven. Sand Dune Metallic (GTL) carried over - GM Authority's pre-production articles list only ten colours and omit it, but the production catalogue shows it on Custom Trail Boss, LT Trail Boss and ZR2, and GM's 2024 order guide records it as a 2024 deletion, which requires it to have been present in 2023. Other per-trim restrictions: Iridescent Pearl Tricoat (G1W) on LT Trail Boss, LTZ and High Country only; Harvest Bronze Metallic (GXN) on Custom Trail Boss, LT, LT Trail Boss, LTZ, ZR2 and High Country (not WT, Custom or RST); Radiant Red Tintcoat (GNT, $495) on LT, RST, LT Trail Boss, LTZ and High Country; Red Hot (G7C) on everything except LTZ and High Country; Summit White (GAZ) and Glacier Blue Metallic (GLT) on everything except High Country.
Where to find your paint code
Driver's-door B-pillar Certification label - scan the 2D QR/data-matrix code (all 2018-and-later Chevrolet, Buick, Cadillac and GMC vehicles) to list every RPO code fitted, paint included.
Driver's door jamb
- Open the driver's door and find the Certification label on the B-pillar or door jamb.
- Scan the square 2D QR/data-matrix code on that label with a phone. It returns the VIN plus the full RPO list.
- In the returned list, the paint RPO is the three-character code starting with G (e.g. GAZ, G6M, GXD).
- If the vehicle predates the QR label, open the glove box and read the 'Service Parts Identification' (SPID) placard instead - it prints the same RPO list as plain text.
- Cross-check against the WA number if you are buying touch-up paint: retailers index by WA, not RPO.
If the sticker is missing or faded
- Service Parts Identification (SPID) placard - glove box on Silverado/Sierra; trunk floor or driver's door panel on cars
- Original window sticker (Monroney), which names the exterior colour in plain language
- Dealer parts department VIN lookup, which returns the build's full RPO list
- GM Vehicle Diagnostics / MyChevrolet app build data for later vehicles

Color availability changed year to year. Codes often carried over; names sometimes did not.
