I'm not sure I got your question right, but that looks like beige and blue-grey?
You certainly have something more specific in mind but I haven't grasped it for sure.
Have you checked the RAL website? Those are universal color references for painters and such.
for Peacock, for example, Zweigart Belfast 32ct 3609 578 Blue Spruce/French Blue or Zweigart Murano Lugana 32ct 3984/522 Colonial Blue
or Zweigart Cashel 28ct 3281/5153 Petrol (Teal)
