Using this live wallpaper app on Android 12, you can choose which color tell the OS to use for Monet feature (no matter what you choose to show in it), which can be used in many apps and on the UI of the OS!

Steps:
1. Choose what to show (image/animation), optionally from your current wallpaper image.
2. Set as live wallpaper.
3. Choose other settings.
4. If you chose custom-colors (for Monet), make sure the OS is set to use the ones of the app (might be called "Wallpaper & style"), and turn off the display after each time you change them, to let the OS use them.

Features :

1. Ability to choose which photo/animation to have as a background, and a color behind it.
2. Ability to have a double-tap to lock the device or turn off the display.
3. Ability to choose which colors to request from the OS.
4. Some experimental flags

Notes:
- This is a live wallpaper app. It means you can't use another live wallpaper app that shows its content, within it. Only one live wallpaper app can be active. This is how Android works. I can't do anything about it.
What you can do is have a normal wallpaper for the lock screen while using this app for the home screen.
- The colors you choose might not be the exact ones the OS will use, and might not affect a lot of apps or even the OS. It depends on both the OS and the apps you have, if they use the colors or not, and how.
- Originally this app was intended mostly for Android 8.1 on Vanilla like ROMs (such as on Pixel, Nexus and Android One devices). Here's a video about it:

- The app's usage of accessibility is only for its feature of locking the screen, and does not collect any information and does not send any information.
