The schemes tended to differ for different vehicles anyway, since they were factory painted in batches & the scheme was not necessarily the same for different batches, yet alone for different types. Overpainting in the field tended to not occur.
Chars Francais has a wide selection of photographs under vehicle type & sometimes with location and date of photo where known. It will at least give an idea as to the scheme for a particular vehicle type. For a couple of examples.
AMD50 Laffly, widely used in North Africa. The presence of FFL personnel suggests North Africa. 2 or 3 colour scheme
Another AMD 50, probably from Syria given the British/Australian soldier. Probaly a 3 colour scheme
