The Tannhauser Matriarchy Troopers come with purple coats, and since they are Russian, I thought a grey winter style would be good as an alternate colour scheme.
I started by painting over their coats with a pale grey, then touching up their bags, straps and belts that I had messed up in the process.
Then I added a wash of Nuln Oil black ink, and they look pretty good. Here they are next to the original set.
This is the back view.
The next set due for a repaint is the Shogunate Trooper pack. They may be a bit more colourful.
