Use the Shortcuts app to recreate monochrome icons for your most-used apps. Some system apps like Settings and the Camera already have grayscale icons, so you don’t need to worry about those.
Who it’s great for: People who like everything neat and tidy but aren’t ready to go full-on minimalist. Also handy for people suffering from some types of color-blindness.

Speaking of recreating app icons, another alternative is to replace your icons with color-coded Shortcuts. Why not make all your work apps green, your games red, and all entertainment apps blue, for example?
Who it’s great for: Anyone who wants to bring order to the chaos of overly ornate app icon designs.
