[WWI] German color question - was "Accurate colours"

[John Ratzenberger]

I do not do German models, yet I find myself with a D.III on the bench.

Can someone give me a decent color match/mix using Tamiya Acrylics for the top-of-wing colors (Dark olive green, pale whitish 
green, and rust brown) and the underside of wing colors (sky blue).  I am particulrly confused about the pale whitish green as 
I've seen models & color profiles ranging all over the place ...

Thanks, and please note "decent match", not "exact" ...
