Remember PROPER surface preparation before Duracoating, it really affect the finish durability.
The above finish is base colour Woodland Tan with dark spots WWII Olive Green.
With WWII Olive Green you can made a wide spectre of colours. Add same amount of white as hardener and you'll have a very nice, subtle green. Picture below is a barrel with said mix next to a blued for comparison.
