With help of this Unity package you will be able to use Material You colors in your projects. It implements several components to control colors of different UI elements. It also can be used in projects which are targeting API lower than 31 (Android 12), because it has a fallback palette for such cases.
Import the package to your project. To do so, open a package manager tab, click the plus button on the left upper corner of it and select Add package from git URL. Then enter a git URL of this repository. You can then add components like ImageMonetColorer to your objects and select needed color with sliders on those components.
Right now there are components implemented in this package for coloring the following UI elements:
ImageRaw ImageOutlineShadowTextCamera Background
However, you can easily create colorers for any component you need. First of all, inherit you component from a MonetColorer base class, then overide the UpdateColor() method as you want. Calling base.UpdateColor() will set the _colorValue and _color fields to a new values, when they are changed.
Fallback palette. If you want a custom fallback palette, customize this file. Currently, there is no tool to create such file, but there are plans to make one. For now you can use my Previewer app and edit its output by hand.
