Hi Grimm,
There was a topic of this subject sometime ago, however, the guys has shown some of the colour variations you could use.
I'm now using a combination of mixing Khaki Grey with English Uniform and then adding some German Camo Brown/Black mix for a darker effect on some attire.
Field Drab and khaki Grey with a hightlight of Iraqi Sand with a soft flesh mix will give you a lovely effect also.
Green Grey and English Uniform is also not to bad either! Green Grey and Brown Olive is another possibility.
In essence you can vary the trousers and tunics with what you like. Bolts of German cloth came into producing Turkish uniforms too.
White is another good colour variation on its own or in combination with the above.
As Poly has mention I like to have my Turkish officers stand apart from their rank & file so I tend to pay more attention to them with regards to colour.
Best of luck to you.
