Huh! No one has even mentioned webbing........
My take on NW Europe; Use the Vallejo Brit. Uniform,use a mix such as chocolate brown for the shade and a beige brown for the highlights,it should be browny not too green.However Canadian made uniforms were greener as were armoured uniforms.
Orctrader I think you may got a dud bottle,I've two bottles of Brit.Uniform,each is different.....one lighter one darker and the difference in colour is distinct.
If you can still get it use Mike Owen's (Artizan Design) Brit Uniform download,excellent and it was free.
