The Apple iPhone interface uses relatively constant colors, and the majority of the on-screen colors can not be altered by the owner. However, iPhone users can invert the overall color scheme of the device. Inverted screen colors can help aesthetically impaired or colorblind users browse the phone and can make text more readable.
1. Access the iPhone home screen and tap the “Settings” app.
2. Select “General” and after that tap “Accessibility.”.
3. Locate the section identified “Vision.” Toggle the “Invert Colors” alternative. When the choice is “On,” the iPhone colors are inverted.
4. Tap the setting back to “Off” if you want to go back to the typical color scheme.
