In this post, we’ll see how to increase color contrast between app foreground and background colors on your iPhone.
Let’s see the steps to do the task (here, I’m using iPhone X (iOS 13.3)):
Hit Accessibility which you can find between Display & Brightness and Wallpaper.
Tap Display & Text Size which you can find between Magnifier and Motion.
Hit the toggle switch beside Increase Contrast, which you can find between Reduce Transparency and Differentiate Without Colour.
