I have just finished the Tamiya Sd.Kfz 222 and thought i would place in a small diorama depicting a vehicle of the 6th Army about to cross the French border May 1940, the problem i have is the uniform of the supplied figure, i have painted it in Tamiya XF65 Field Grey which is actually very green although on the box art the figure is in grey uniform? could somebody point me in the direction of a good reference book or help with paint colours please.
