If you’re running the iOS 18 or iOS 18.1 beta, you can give the Facebook app icon a new look by long-pressing on the Lock Screen. In Jiggle mode, tap the Edit “pill” in the top left corner and then Customize. A pop-up menu on the bottom of the display gives you the option to return the icons to put them in Dark Mode, return them to the traditional colors in Light Mode, have them change from Light to Dark Automatically when the sun sets (and vice versa when the sun rises), or tint the Home Screen app icons in different colors based on the two sliders at the bottom of the display.
