from what i understand the captured color scheme you see adopted by this particular fighter group (79th fighter group, 12th usaaf) was an attempt to provide quick identification of captured aircraft. since some of the aerial engagements were subject to atmospheric conditions(clouds, sun, haze/fog,etc.) it was extremely important to be quickly be able to identify these aircraft as non-threatening and not a attack element. the colors were pretty much limited to theatres of combat. i think the stateside captured aircraft had their national markings reapplied with a "fe" or foreign evaluation number applied. at least comtemporary photos seem to suggest this. hope that helps,h.whiteman.
