This screenshot of Hengsha looks a lot, color wise, like Montreal in the winter. About 20 years ago, they changed the street lamp gas in the (Québec) province and everything get a golden hue from snow reflecting the light.

So far, I love the color palette for the game. The other two games were always at night, with grays and more grays as a color palettes. And not all the game is "black & gold". There's whites and blues. The first one is a screenshot (here's a concept art of the same room), the other is a concept art.
