Paint code GBA · solid paint
Onyx Black
Onyx Black carries Chevrolet factory paint code GBA as a solid paint finish. On a Chevrolet, you'll find the code printed on the Service Parts Identification (SPID) label in the glovebox — the paint appears as an RPO-style code (e.g. GAZ) alongside a WA paint number on many years. The swatch shown is representative — lighting and screens shift color, and a respray won't change the code the car was born with.
