Jcb, More on camou history, if you're curious...
Early war (we like grey, Dunkelgrau and lots of it... or Gelbbraun fur Afrika)
On 1940-06-12, it was ordered that units would be issued paint, rather than having to buy it from the suppliers, and that only Dunkelgrau would be issued. On 1940-07-31, it was ordered that all tanks should only be painted in Dunkelgrau Nr.46. This was in order to save paint. Dunkelgrau Nr.46 was renamed Dunkelgrau RAL 7021 on 1941-02-10. On 1941-03-17, it was ordered that all vehicles in Africa should be painted Gelbbraun RAL 8000 and Graugrün RAL 7008, with the base colour being Gelbbraun RAL 8000 with one-third of the base colour covered by Graugrün RAL 7008. The edges should be feathered. The areas to be painted with Graugrün RAL 7008 was not to be painted with Gelbbraun RAL 8000 first, though. Small items shoudl be painted in only one colour. On 1942-03-25, it was ordered that Braun RAL 8020 and Grau RAL 7027 was to be used in stead of the current colours in Africa, once stocks of Gelbbraun RAL 8000 and Graugrün RAL 7008 ran out. The pattern was to be the same. All four colours were matt. It is sometimes seen that vehicles in Europe in this time period are sometimes seen with a two-colour pattern, even though it wasn't authorized. The commonly accepted explanation is, that these are vehicles which were meant to be send to Africa, but for one reason or another were never send.
As you'll see, Dunkelgrau is great for Dieppe, but not so good for Russia (below), lol
Late war (let's get funky with patterns)
On 1943-02-18, it was ordered that all vehicles were to be painted in a base coat Dunkelgelb nach Muster (except for small equipment pieces, which were to retain the former colours). Over this, a camouflage pattern of Olivgrün (an RLM colour), Rotbraun RAL 8017 and Dunkelgelb nach Muster consisting of stripes was to be applied by the maintenance sections, according to the terrain. For this purpose, the paint was delivered as a paste, which could then be thinned with most liquids, and applied. Dunkelgelb nach Muster was later re-named Dunkelgelb RAL 7028, and Olivgrü was re-named Olivgrün RAL 6003. On 1944-08-19, it was ordered that the tanks should be painted at the factories, in order to achieve more standardized patterns. The pattern used, called Hinterhalt-Tarnung, consisted of a base of Dunkelgelb RAL 7028, with Olivgrün RAL 6003 and Rotbraun RAL 8017 stripes. On top of this pattern were added small dots of all three paints.
In mid-September 1944, the tanks were were left in the red primer as the base coat, with only limited camouflage applied by the factories. On 1944-10-31, this order was expanded to include that both Dunkelgelb RAL 7028, Olivgrün RAL 6003 and Rotbraun RAL 8017 should be applied in limited amounts over the red primer, and that Dunkelgrau RAL 7021 could be used in stead of Dunkelgelb RAL 7028 is no Dunkelgelb RAL 7028 was available. There is no evidence that Dunkelgrau RAL 7021 was ever used, though. On 1944-12-20, it was ordered that the base coat should be Dunkelgrün RAL 6003, with a hard-edged pattern of Rotbraun RAL 8017 and Dunkelgelb RAL 7028.
Whitewash (Barbarossa in one word?)
Because Dunkelgrau RAL 7021 presented a very stark contrast against snow, OKH decided to provide the troops with white paint to paint the equipment during the winter. The paint was water-soluble, so that it would run off the equipment when the first rain started to wash away the snow. To prevent having to re-paint stencils, tactical numbers and unit emblems, these were often left without whitewash. Because of the large distances the whitewash had to be transported, and relatively small supplies of whitewash, several vehicles only received whitewash sparingly, if at all. Some units had to be creative, using chalk or even sheets to provide some kind of camouflage. Stacked snow on the vehicles was also used. Some of these interim solutinos were obviously better than others, also depending on the conditions. For example, where a sheet cover would blend in very well against a snow-covered field, an iregular pattern would be more suitable against a wood, where the trees would be left uncovered with snow.
Camouflage (now that's what I call sneaky!)
Although Germany didn't use camouflage netting or tarpulins on any great scale, they can still be seen on a few photographs. Some of these are definately German army issue, as they are seen on pre-front photographs, however others may simply be captured netting and tarpulins. Especially until 1943-02-18, the dark colour of Dunkelgrau RAL 7021 and Dunkelbraun Nr.45 could make it difficult for the vehicles to blend in properly, however while driving, a lot of dust or mud (depending on weather conditions) would quickly cover the vehicles. Although mud would have to be removed from movable areas, it could still provide a camouflage effect, and has even been seen intentionally smeared over vehicles. In Africa, some of the Dunkelgrau RAL 7021 painted vehicles were even painted with such mudpaint, made from desert sand and water. Especially in the latter part of the war, Germany used a lot of foilage as camouflage, to blend in with the natural suroundings. Branches, small trees and even hay was used to disguise the vehicles, sometimes with better results than others. As the war progressed, and the German troops were retreating, large piles of pre-cut branches were sometimes arranged at roadsides, for crews to help themselves.
