Hi,
no, Italian armoured vehicles are painted dark green, not a brownish color as Olive Drab. I have not chips, but it could be not far from the NATO dark green of Tamiya. If faded, it appears lighter, more or less as fs-34102 (Gunze 303).
Now, I have a question because I am starting a kit of Trumpeter of a Centauro, and I am thinking to paint it with a white livery of UN.
Well, is the white color extended to the lower part of the tank, suspensions and inner disk of the wheels, or they have to remain green? The drawing of Trumpeter shows them as all white, but it's a drawing only.
Who can say it for sure?
Again: I am interested in experiences and suggestions from anyone has already built this kit.
