Opel’s German documents connect paint choices with Corsa special editions, Astra references and Frontera equipment packages. Each color record identifies the evidence behind its code and explains the effect of choosing it, including roof options and trim restrictions.

The drying step behind Opel’s three-wet terminology
Opel’s June 2022 account of Kult Yellow for the Astra also discusses the Rüsselsheim paint shop. It calls the production method three-wet and says it removes a complete drying step. That term identifies a manufacturing process, rather than a paint name or ordering reference.
The manufacturer’s colour-development article is useful background when reading about the yellow. Its factory-process description does not supply a refinish recipe for an individual car.
