One thing for certain is that in skinning, whatever color looks best is the right color

. US planes are in much better condition than LW or IJN/IJAAF planes in the fact that a variety of sources and planes referring to the exact colors still exist.
When I was skinning LW planes, many sources always contradicted each other and it was very hard to really verify which colors were 'historic' and which were 'popular misconceptions'. In the end, I had to use mixed references from mixed sources so the plane just looks 'pretty', but still feels much 'historic'

So technically, all of the skinning work for LW planes I did were, in the end, just 'speculations', and probably 'semi-historic'.
I'm not sure how camo paint was applied to each planes, but I'm guessing it didn't come from a universal supplier in exact same colors everytime. At least, for the Soviets, who also saw large changes in paint schemes during the war years, I know that in many cases only the 'guidelines' were received from High Command and each of the squadrons just mixed up paint colors according to it. So the planes of the same squadrons would sometimes have different shades of green or grey, and some might be using the old scheme while others were using the new scheme.. and some in winter camou and some in summer.. etc etc..
Just make it look pretty, and the odds are, what feels 'right' to most people is probably really 'right'
