2020 Chevrolet Silverado 1500
10 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.
Changes from 2019:

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.
