>>10798428>if you paint blue over a black piece, it'll appear differently than if you paint blue over a white pieceOnly after 1 or 2 coats if your paint pigment density is particularly low. After 2-3 coats primer color makes 0 difference. Primer makes sense for adhesion and fixing surface imperfections but for color modulation it is a meme. In fact, if your color is affected by the color of the primer underneath it means you have not applied enough paint and you are not getting the actual color you expect.
One exception: black/brown primer for when you expect spotty coverage in hard to reach areas, in which case dark spots from bad color coverage would look like natural shadows.
