Just out of curiosity which color top coats do you use over a white primer?  I ask because with all of the models I've done the last couple of years since I got back into the hobby for the first time in decades I've only used gray primer.

Here is a sample of the effect of four different colour primers. The paint is Tamiya LP-46 Pure Metallic Red.  All were sprayed with equal coats.

Well thank you very much for that image Greg and clearly there is a distinct difference amongst the spoons. This is good information as I happen to have a couple cans of Tamiya TS-18 and I'll be able to alter the appearance of the paint from one model to another.

It is pretty interesting how the color varies with primer darkness, who'd a thunk it huh????

I don't find that too surprising.  Some paints (especially light non-metallic colors) are not perfectly opaque (especially applied in fairly thin coats, as we do when painting models).  So whatever color is under the paint will partially affect the final color.    The darker the paint, the less of an effect the underlying color has on the final color.  But as a general rule, it makes sense to use a primer which is not too contrasting with the final coat.  Even some metallic are partially translucent (again, in thin coats).  Depends on how dense the metal particles are.  Actually surprisingly white is usually quite opaque, but I still would not use dark gray or black primer under white.  Yellows and oranges seem to be the most translucent.
