I am currently using a Realme device which runs on Android 13, When i set my app icons to match wallpapers color a few of them are staying as they are as shown in the screenshot. Is there any way to customise these aswell with the help of any 3rd party apps? This just doesn’t look right.
You will need an icon pack and/or a 3rd party launcher application. Pix Material You Light/Dark(paid) should fit the bill. Smart launcher 6 also has an option for themed icons.
