Primed in Chaos Black - I primed in black as I’m using an airbrush to base coat my yellow. Sometimes I have trouble with the yellow coating the recesses evenly, so anything missed by the airbrush will be darker, which is desirable, though not ideal. If I was using a paint brush for my base coat, I might prime in a lighter colour.
