I thought the colors were decided, but if not, I would like to put in my vote for BBQ/NN as well. Plus, I think that is what most people would want out of this set. However, BBQ does not look bad on dark gray. The soware mods actually use BBQ on a dark gray. It looks good but lacks the contrast of BBQ on black. BFQ is way too light and washed out for my taste, even on black. BBJ is too dark for my taste on dark alphas. The soware windows, menu, and non-stepped caps-lock keys actually use BBJ on dark gray instead of BBQ. Googling that set will give you an idea of how these blue colors look on dark gray.
