Here is the picture that I was talking about. This color photograph shows that the this Tunisian Tiger I is green not Sand Brown (Ral 8020). Field Green is not the exact color, maybe a mix of different greens is needed to match the appropiate colour. Also this photo is very old (1942 - 43) and the real green can´t be appreciated here.

Te following text was extracted from the page that can be found in the next link:

"The first Tigers issued to front line units during mid-1942 were delivered in overall Dark Grey (RAL 7027). In the Winter of 1942-43, washable White paint was used as camouflage in snow-covered areas. The Tigers of sPzAbt.501 , which deployed to Africa during late 1942, were camouflaged in Desert Brown (RAL 8020) and while Dark Gray was authorized to be used as a second color in a disruptive camouflage pattern, there is no evidence that sPzAbt.501 ever painted their vehicles in this manner. In the more temperate climate of coastal Tunisia, many of the tanks of sPzAbt.501 were oversprayed with Olive Green (RAL 7008) to enhance their camouflage."

How accurate is this picture as far as color? When looking on the DAK website, you can clearly tell that many photos have been colorized. There are several original color ones on the site along with B&W. Am I being too skeptical about the origins of this photo?
