Assassin's Creed Black Flag Resynced includes a yellow-tinted visual filter common in games and films depicting warm tropical settings. The filter, sometimes referred to colloquially by players, was intended to enhance the atmosphere but has prompted modding solutions for those seeking alternative aesthetics.

Modder Blu has released ACBlackFlag Natural Colors, a Reshade preset that removes the yellow overlay and adjusts colour saturation to restore a more naturalistic appearance. Players can supplement this with additional community mods that provide technical improvements, including uncapped framerates for cutscenes and expedited startup sequences.
