I'm thinking the factory two-tone Dusk and Driftwood Gray would be a nice combination.

Be sure to seal that red plastic thoroughly.
Uusually, I recommend silver paint over gray sealer-primer for the best results, as the paint will block the leeching colorant and not show too much discoloration. Top-coat that with white primer to be sure you're getting a good base color-wise to start with, given how light the Driftwood Gray is.
Interesting, given that I've never had a primer "leach" its color into the finish (and I've been painting model cars for at least 54 years now. Part of the problem with color coats can be that they are mixed from a combination of pigments and "toners", the latter of which are transparent, very much like dyes, and can bleed at times into color coats (reds are, in my experience the worst offenders at this). True primers, on the other hand, generally don't have toners in them, the most common, red oxide, white, gray and black, are, I believe, all pigment, with no toners or dyes in them. Of course, whenever I use anything as a primer, it is that, just that: primer, made and packaged as such.
Now, with colored plastic, red being the prime offender, often times styrene gets "colored" with dyes, particularly reds and yellows, and those will bleed through most paints at times, although I have never had that experience (I dunno why--either I've been lucky, or the red plastic demons are scared of my disposition?) This situation does require a sealer of some sort or another, in order to prevent bleed-through.
