Change color on iPhone to make it easier to see items onscreen
To make it easier to see what’s on your iPhone screen, you can invert and filter colors or make transparent items solid.
Tip: Quickly set brightness with the slider in Control Center.
Invert colors
You can invert colors on the iPhone screen to make it easier to read text. This can be especially useful in apps and websites that don’t support Dark Mode.
Go to Settings
> Accessibility > Display & Text Size.
Turn on one of the following:
Smart Invert: Reverse colors everywhere except images.
Classic Invert: Reverse all the colors onscreen.
Filter colors to adjust hues
Go to Settings
> Accessibility > Display & Text Size.
Tap Color Filters, turn on Color Filters, then tap a color filter to apply it.
You can drag any slider that appears to adjust the intensity or hue. The pencils reflect how the filter affects a range of colors.
Note: Color filters can change the look of images and videos.
Turn on Reduce White Point to tone down the intensity of bright colors.
To have screen colors become warmer as it gets dark out, use Night Shift. Night Shift automatically removes inverted colors and color filter effects (except grayscale).
Make transparent items solid
Some backgrounds appear transparent or blurred by default. You can make these transparent backgrounds opaque by giving them a solid color. In this way you simplify those parts of your screen and make them easier to see.
Go to Settings
> Accessibility > Display & Text Size.
Turn on Reduce Transparency.
Differentiate without color
Some screen items rely on color to convey information. You can replace these with alternative ways to tell them apart, like shapes or text.
Go to Settings
> Accessibility > Display & Text Size.
Turn on Differentiate Without Color.
Use ones and zeros for on/off switches
Switches turn green when they are on. You can also have switches use “1” to indicate when they’re on and “0” to indicate when they’re off.
Go to Settings
> Accessibility > Display & Text Size.
Turn on On/Off Labels.
To apply these settings to only the contents of the zoom window, see Zoom in on the iPhone screen.
You can also use Magnifier to change the colors you see in your environment. See Change Magnifier settings on iPhone.
