It will depend on how much notice your troops had. Very short notice and the vehicles would probably be black and green camouflage or plain green overall. The actual shade of both depends on when and where it was painted, how much thinner was used, brush or spray paint etc. Camouflage was done by the unit.

Given a bit more time a scheme like this one in Kenya might be used.
In Africa colours fade. Dust distorts the colours. Sand and vegetation rub the paint. So you really have a wide choice of colours!
