How do I set no wallpaper (completely black) on Android?

I've just got a new Samsung Galaxy S22 phone and wanted to customize it. I wanted to have just a black screen as background, but I could not find any way to do it. On S22, one needs to choose some wallpaper, there is no option None. Then I checked my old phone and a new tablet - same there. Then I checked all the questions here filtered by "android wallpaper" - and found nothing. Am I missing something, or is it really not possible to have "wallpaper: None" on Android? (just simple black screen background.) (I know I could use a black colored image as wallpaper, but is it such a "hack" the only solution?)
