Need Some Swiss Bf 109G-6 Color Help

I am getting ready to build the Tamiya 1/48 Bf 109G-6, kit 61117 and I want to paint do it in Swiss markings. I already have a decal set for it, but need some help figuring out what colors to use for the upper surfaces.
The aircraft I am doing is marked J-704. Apparently, this aircraft had an experimental camo scheme applied by the Swiss. It is a green and brown(ish) scheme, but the decal set doesn’t indicate what colors they were.
So, does anyone here know what colors were used?
Thanks a bunch in advance.

Brett, I found this on a quick Google search. It also mentions the used paints. Hope it’s of some help for you.
