I recently purchased a 1/144 scale Shuttle atop the SCA (747) model. I want to use the correct colors but am still uncertain. The 747 is mostly white but the bottom is either light grey or silver. From photos, I can't tell. Also, I always thought the bottom of the Shuttle was black but now after looking at photos, it appears the heat shield bottom is not black but is really grey. Any expert out there about such things?
