Granpooba, as to the color of the aircraft, most (but certainly not all) builders try to recreate aircraft that inspire them in one way or another. Or they pick one that just looks good. But I have built some that were how I would have painted mine if I were flying back then. My DVII is a plane from Marine Jagdgruppe Flanders and is done in cub yellow. I have been told that cub yellow did not exist then so how could I use it on my plane? I say prove it did not exist in 1918. They most certainly did not call it "cub" yellow, but they had yellow, so who knows what the shade was?
