I have a rooted oneplus 3t phone running Android 9 on a Lineage OS that I wish to style after the Fallout game franchise. I have many details figured out, except that the status bar color only seems to have the option of black or white. I would like the status bar icon colors to be green. This would especially be helpful as I've noticed that these white icons burn into the screen when a phone is old enough.
I first tried GravityBox which took forever to install only to find that they removed the status bar color tweaking features out of respect for other android releases that gave us this option by some other means... but Pie took them back.
I also tried Substrathum which gives an error page saying "Could not fall back to rooted mode. There are no other theme engines able to be utilized on this device at this current time." I found some sources which claimed to have it working on Pie, but their instructions were unclear or not specifically useful for getting past this error in Pie.
Can anyone help?
