No idea what the instructions call for, but the actual colors look to be black, forest green, and dark tan.
The interior is most likely flat black in the cockpit and medium grey in the rear cabin, just like US aircraft. They are like this due to NVGs washing out if the cockpit is a brighter color like grey.
