How to Enable and Use Dark Mode App Icons on Your iPhone with iOS 18

iOS 18 introduces the ability to change iPhone app colors natively, allowing users to choose Dark Mode, Tinted or Automatic switching between Light and Dark Mode. To use this feature, you must be running the iOS 18 beta on your iPhone (full guide). From the Home Screen, press and hold in an empty area, tap Edit in the top left corner, pick Customize, and select Dark, Tinted or Automatic. This feature currently applies to all apps, not individual ones, and both first and third-party apps.
