So, is the original a light green like in the pic i posted, or that olive drab in your pic?
I think the light green looks much better on the airframe IMO.
did you look at the colors around the prop? i'm betting the "areteest" who painted that image you found thought the same as you. it just wouldn't be correct though. olive drab was an easy color to find in the supply depots. almost all military vehicles and some aircraft were painted with it.
whether or not the light green is historically correct around the nose is another story.
