Material You is the theming framework that allows phones and tablets running Android 12 or higher to use your favorite colors throughout the user interface (UI). Introduced back at Google I/O 2021, it launched first on Pixel phones last fall and then incorporated into other Android devices through Android 12L. 

It relies on something called the Monet theming engine, which pulls colors from your phone wallpaper and seeds those colors throughout your buttons, Google apps, and app icons. Google encourages third-party developers to incorporate customizable colors into their apps’ UI as well.
