Thanks for posting, I love seeing alternate color morphs like this. (I am just glad it was not some type of small cat, or I would have to go into debt to fly to Germany to photograph it ).
Hard to say! I saw a stuffed albino which was a lot whiter however there was another in the same collection that was quite like this one. Both were shot in the wild, and full grown! I suppose not many animals will tackle an adult badger and they stay close to the burrows when they are young and vulnerable.
I'd go for hypomelanistic. It could be missing eumelanin. In the bird world it would probably be called cinnamon or fallow (depending on its mode of inheritance).
It made me think of the brown giant pandas in China. As for those animals, inbreeding supposedly caused the replacement of all black coloration with brown colors.
