I have a dilemma, or possibly a trilemma if such a thing exists. I am watching the DVD “The Battle of Westerplatte 1939” and it appears that the Polish khak uniform is significantly greener than most painting guides suggest – assuming the film makers got it right and my TV colour balance is correct.
So, looking at the title photo on this post, should I:
a. Try to repaint these fellows?
b. Paint their reinforcements as their existing comrades?
c. Use a greener tint and claim it was a different issue or that colour has faded in the field?
A second question. Does anyone know which of the two tents in the photo would be more appropriate as to colour for Polish forces in 1939?

I would just leave them as they are, unless it bothers you. Most painted Russians that I see are Khaki, even though the summer uniform started off as a greener shade, until it faded.
