2019 Chevrolet Silverado 1500
11 factory colors were offered on the T1XX (fourth generation), pre-refresh Silverado 1500. Your code is on the driver's door jamb sticker on the line marked C/TR — the characters before the slash.
This is the earliest model year currently in our database for the Silverado 1500, so there is no prior year to compare against.

Roster is for the all-new T1-platform Silverado 1500. The carryover K2XX-based 2019 Silverado 1500 LD was sold alongside it with a different palette (it included G1K / WA-409Y and GPA / WA-457B, neither of which was offered on the T1 truck) - those are deliberately excluded here. Trim restrictions from the Chevrolet catalogue: Iridescent Pearl Tricoat (G1W) is $995 and not available on WT, Custom or Custom Trail Boss; Cajun Red Tintcoat (GPJ) is $495 and not available on WT; Red Hot (G7C) is not available on LTZ or High Country; Summit White (GAZ), Silver Ice Metallic (GAN) and Shadow Gray Metallic (GJI) are not available on High Country; Oakwood Metallic (GE0) was a late-availability colour, not offered on WT, on Double Cab bodies, or with the (BRS) power assist steps.
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
