A lot of games tend to have a distinct visual style. Fallout 3 is green, Red Faction: Guerrilla is orange, and a lot of the Battlefield series is blue. Some fans didn't like the tints they saw in the Battlefield 6 beta and removed them, but one developer says there's no filter, just the "vibe" of each map.
Over on Reddit, one post shares a side-by-side comparison of one map in two different visual styles. The original, as the developers intended it, is much colder, the trees darkened and the clouds a deep gray, assault rifle a steely blue. It's a dark, gritty warzone.
