There is a very interesting (IMHO) camouflage shown in a You Tube film.

Here is the link:

The contents of the film in German is as follows:

Tank in service of nation preservation measure
The tank creates small depressions in the earth to make the mountain-grasshopper (Gebirgsgrashüpfer) able to put down their eggs in them. The crew by KMW does this job on the former training airea Muensingen with much joy.
A biologist gives advises for the route the tank has to go. This same route is done four to five times. As the action has proved to be successful they hope that KMW will do it again. This nation preservation measure has been paid by KMW.

I think this Leopard shows a selection of the colours seen on the Leopard 2 A7+ during Eurosatory 2011.
