FMM, I can't find a reference to white. The B had red arctic colors, which would be pretty cool, but that's a minicraft 1/144 model. Otherwise, they are natural aluminum and magnesium, with silver paint in some places.
There's two big glitches in that otherwise fine model. The first is the leading edge intakes, which if you get a good photo of are bigger and more curved than the model. Easy to fix with a file. The second, which is hard to fix, is that the wing upper surface is continuous across the fuselage, rather than the other way around, as in the model. It means a cross of masking tape, and a bunch of putty, but it looks better if you do it.
