Hi Bob. I used Tamiya acrylics for the roundels. They are just the basic xf colours without mixing. They look ok to me. The PC10 is a mix of several colours. Just kept mixing till I liked the colour. Couldn’t tell you what’s in it anymore. The silver is the new Tamiya lacquer range silver and the purple is a lacquer from sms (which sprays really well). Looking forward to seeing your XII.
