After Traffic and Breaking Bad used it for scenes set there it became know as "the Mexican filter", though it's sometimes used for scenes set in South Asia or anywhere a bit tropical. You may recognize it as "the piss filter" that stained the original incarnation of Deus Ex: Human Revolution. It's the yellow gradient that's usually intended to make things look warm, and it's not to everyone's taste. Like piss, I guess.
Assassin's Creed Black Flag Resynced is the latest videogame to fall under the stream, making Edward Kenway look a bit more tanned and the waters look a bit more green. I didn't think it was particularly excessive until I saw some before and after screenshots with it removed, and yeah, it does seem a bit dehydrated actually.
These images come courtesy of Blu, a modder who has cooked up a reshade called ACBlackFlag Natural Colors: "A simple reshade preset that removes the ugly yellow filter from the game and corrects oversaturated colors."
You'll need the latest version of Reshade to install it. While you're at it, the ACBlackFlagFix will let you uncap the cutscene framerate, set cloth to animate at 60 fps, and remove pillarboxing, while Fast Launch will get you through those annoying startup videos at a rate of knots.
