Dark Red to Dark Blue - Prime?
This is where quality of paint is everything.
Deep colors require lots of pigment, and the usual pigment (universal tints) ,if not locked in the resin will wipe off.
BM's Aura is about as fail safe for not doing that or burnishing than any paint I know. It uses a pigment system ( genex) that becomes part of the paint more totally. That is why it is worth the price.
IMO, of course..
