If you choose Tinted app icons rather than the Dark style, iOS applies a different algorithm to change the colors of icons. Tinted icons feature an accent color on a dark black background.

Here’s how it works. Light, Dark, or custom tint To change the appearance of an icon, start with a long press on your home screen in an area where there is no app icon for a couple of seconds.

Apps and widgets are now finally free to go wherever. So long as you stay to a grid pattern, you can now place app icons only in the bottom part of your screen, or just on the sides, or in a zig-zag.
