Paint colour code 303XI
Standard shade
We mix 303XI to the standard factory shade for this code. Paint fades and shifts with a vehicle’s age and sun exposure, so an older panel may not match exactly — bring in a sample panel or part and we’ll match to it instead.
Looking for the GMC 303XI colour code? This is Dk. Atmosphere, a solid finish used on GMC vehicles 2017 - 2019. Order it mixed to code below, from a touch-up bottle up to a full 5-litre tin.
Pick a size below — the colour, code and make are already filled in for you.
Tell us the colour to mix — a name, a code, or both.
If it came off a vehicle, this helps us match the exact factory shade.
The same steps whether you’re spraying a full panel with a gun or touching in a stone chip with the bottle brush — just fewer coats and a smaller area for touch-ups.
Not on sound existing paintwork — spraying straight over a clean, keyed surface is fine. Bare metal or bare plastic needs primer first (see step 2 of the full respray guide above).
No — Dk. Atmosphere is a solid single-stage colour, so the touch-up bottle is the finish coat with no clearcoat step needed.
Plenty for stone chips and small scratches. For anything bigger than a coin-sized area, or more than a handful of chips, go up to the 150ml or 250ml size in the builder above.
The same Dk. Atmosphere mixed to code either way — the aerosol is the basecoat pre-loaded into a spray can for panel-sized touch-ins, while the tins and bottles are for gun or brush application.
