   This thread never needed to be asked if the OP read the tutorials written   
   on this subject, so suffice to repeat one more time that all of us have   
   been informed that many Android phones (especially Samsung, Pixel, OnePlus)   
   allow us to set a solid-color wallpaper, including pure black.   
      
   Even if the stock OS doesn't include it, almost every Android launcher or   
   wallpaper app can do it (e.g., mine can, but it depends on the launcher).   
      
   So the net summary is that Android allows black and any other solid color,   
   either through the OS or the launcher. It depends on the OP's setup.   
      
   Like some Androids, my newest iPad, which I just checked for confirmation,   
   does what my Android does also, so both platforms have the same capability.   
      
     Settings -> Wallpaper -> Add New Wallpaper -> Color (18 exist)   
     It doesn't seem like there are any others though, than those 18.   
     However you can slide a bar below them to change the brightness.
