Learn how to change the color tint of your iPhone’s display…

Color blindness can be a hassle at the best of times in the real world, and it’s a problem that remains when using your iPhone to browse the web, examine photographs or generally interact with the user interface.

Thankfully there’s a built-in accessibility setting which adjust the color palette of the display to accommodate for color blindness, making it possible to see tricky colors in a wide range of spectrums. Here’s how it works:

1. Open the Settings app and go to Accessibility > Display & Text Size > Color Filters then toggle Color Filters on.
2. You’ll see a preview of the effect in the graphic at the top of the screen (scroll it left to see two color charts).
3. To fine tune the color spectrum change, tap the filters below the image.
4. You can adjust the intensity of the effect using the slider at the bottom of the screen.
