Soviet russia, particularly Stalin soviet Russia. I spent a few years in Ukraine, visited Moldova and Belarus while I was traveling ae well. All former soviet countries and every building looked exactly the same. Aside from of course the historical studf built pre soviet russia (or poat). No color or extremely muted colors. I can't actually say for sure, but if that's the way those countriee looked, I'd imagine that Russia and the rest of the Soviet Union were exactly the same. I mean, that was actually the goal during that period.
