This was an absolute scourge on gaming in the 2000s. I remember when gears of war came out on PC and the most popular mod simply removed post processing effects from the game. It instantly went from poop brown to James Cameron Terminator 2 judgement day Blu-ray edition levels of teal.
I think the teal was better TBH.
Remember when uncharted came out on the PS3 and there was a feature in the menu called "Next-Gen mode" that just put a brown filter over everything?
