Early in the war most tanks were panzer grey. Later and as air supremacy was lost by the Luftwaffe hiding 50 ton plus tanks became more vital. Dark Yellow (Dunkel Gelb... auf Deutsch) was a base color over the red oxide primer. A pair of 2 kilo blocks of paint base (Grun und Rot Braun most often) went with the tanks to the field. Most were painted in the field by the repair/maint. units with a pressure feed spray gun. The paint base was mixed with thinner, kerosene, petrol/gasoline, even water ...and this resulted in a WIDE variety of camo patterns. These were tailored to suit the theater of operation, season/time of year and terrain. I think that this variety is why the German tanks are so loved and duplicated.There is a favorite pattern for each of us to adore....
The Olive Drab of US tanks gets boring fast. The Russian tanks are very close behind on the boring scale. The German Tri-color pattern is very popular and the Ambush pattern is my favorite. The red oxide was more prolific in the last stage of the war and broad stripes became very easy to apply in the field and were effective in hiding the tanks. Cut local foliage, hiding in the trees and covering track marks became more vital to evade the Jagdbombers (AKA Jabos). Anti-acraft machine guns were added to many turrets and tank engine decks to fight off attackers. Cuise the web and the photo callery here on RCU to find oyour favorite. Remember, if you grow bored with your Tigers camo you can always cange it later.
