How can I invert the colors for only a given application on Android? (and not for all applications) How can I invert the colors for only a given application on Android? (and not for all applications)

Turning on the "color inversion" option in the settings invert the colors for all applications.
Not possible on stock Android. Google help clearly says :


  Color inversion applies to everything on your device, including media.


If you are on Android 10 using Dark theme and Color inversion together as explained (see link) may be an option in some cases.

If you root your phone and install custom ROM that supports per app color inversion, you are lucky. AFAIK, there isn't an app or Xposed module available for this purpose
