The German Panzer Museum in Munster has a staggering array of WW2 vehicles and visiting places like this helps to get a wider visual impression of the models we paint as well as offering inspiration to paint more realistic camouflage patterns. A quick scan of say painted 15mm WW2 German tanks on eBay shows a wide impression of what many believe camo on late war tanks looked like, but actual examples in museums can be very different to these models.
This Jagdpanzer IV is a good example showing a common pattern of camouflage used. This was applied often by a tired tank crew and done with large, often dirty and grubby brushes, so there is room for interpretation: nothing was done to a template. The aim was to break up the uniform appearance of the tank and made it blend more with its surroundings, which is always worth bearing in mind when painting the models.
The rear of the tank was often just in dunkelgelb as seen below.
