This section gives you step by step instructions on how to apply Colour Filters in iOS 15, with pictures of the screens to help.
1. Tap the Settings icon on your Home screen to open the Settings app. Scroll down and tap Accessibility.
2. On the Accessibility screen, tap Display and Text Size.
3. On the Display and Text Size screen, tap Colour Filters.
