Many apps are now supporting Androids new feature that was introduced in Android 13 called Themed Icons.
This is part of Androids 'Material You' and when turned on in the system settings allows the supported app icon (adaptive icon) to match the colour of the currently displayed wallpaper.
Most of the apps on my phone have already implemented themed icons and look great.
I'm hoping this is something Smarty could easily implement as it's just a vector graphic with a few specific monochrome layers and as the Smarty logo is designed with just 2 spot colours it already lends itself to being used as a themed icon.
