Assuming you mean vehicles:
It was a very brown, cowpat-green. Ostensibly the same colour as that used by West Germany, but always looks even more brownish to me. A brownish WW2 US Olive Drab is a good match.
The three-colour camo didn’t appear until the late 1980s and there were still plain OD vehicles appearing on Bastille day parades well into the 2000s.
In case you mean uniforms:
They used plain OG uniforms until the 1990s.
