For certain individuals that are visually impaired, inverting the colors of the iPhone and iPad screen may make text easier to read, particularly for users who are colorblind, or partially colorblind. The ability to invert screen colors is a built-in accessibility option that comes with all iPhones and iPads. So whether you yourself are visually impaired or you know someone who is, inverting screen colors may enhance your experience while using iOS.
How to invert screen colors on iPhone and iPad
Launch the Settings app from the Home screen of your iPhone or iPad.
Tap on General.
Tap on Accessibility.
Turn On the option for Invert Colors — it's under the Vision section at the top.
You'll notice the screen colors will now invert and somewhat resemble a photo negative. This can make it easier for those with certain visual impairments to pick out content and navigate easier. You can pop back into Settings at any time to disable it if you'd like to later on. You can also set the triple Home-click action to invert colors so you can do it on the fly without having to navigate through the Settings app. If you aren't sure how, you can follow our guide:
