Hi Greg: The propeller hub, leading edges and also most times the tail in white, like in Dom's model photo above, was a New Guinea theatre marking, aldo shared my American P-39's, P-40's and P-47's. After Sept. 1943, Kittyhawks in this area "were required to carry the white identity markings." I've always wanted to paint me up a few planes in those, maybe now I should :)
The Australian P-40's were initially left in their delivery colors, like Dom says, but many were later on repainted in the more tropical Aussie variation of RAF Dark Green and Dark Earth, which were Foliage Green and Earth Brown.
Foliage Green is a more saturated, or vivid, and darker shade. Dark Green is a little closer to olive, while Foliage Green has a bit of a bluer tint. A dark, intense, pine green.
Earth Brown was introduced in July 1942. It was more similar to the UK RAF Dark Earth, only "two shades darker", to allow for weathering turning it lighter. Most illustrations I have in my books picture it a tad more olive than the muddy RAF Dark Earth.
Underside colors were left in the American version on the greenish gray Sky Type S, which was almost identical to the British color, and some were in Sky Blue, that elusive greyish light cyan shade.
Camouflage variations are many, and the norm was to have a mix of colors in the same squadrons. During overhauls, Foliage Green was painted over the Dark Green leaving the Dark Earth as it was, or sometimes also overpainting it with Earth Brown. Olive Drab were repainted when overhauled into Foliage Green/Earth Brown. Some planes were painted fully Foliage Green (like the model above), although never fully Earth Brown.
The camo pattern the Australians used were the same meandering standard A and B schemes the Brits used, so that's easy.
