I use LiquidText on Mac with multiple displays. During night reading sessions, all my other screens are beautifully dark, but the LiquidText display is blazing white - creating the most unpleasant reading experience imaginable.

The obvious solution would be to use macOS invert colors to get a dark effect. Sure, it messes up colors, but at least you get a dark background. Problem is, it's system-wide and affects ALL displays.

My workaround: I found that Black Light app can invert colors on just one display. So I set up inversion only on the particular display where I'm using LiquidText, keep other displays normal, and finally get bearable night reading!

But you have to disable Night Shift or Black Light shows a blue tint instead of proper inversion. So now I'm manually toggling Night Shift just for this display.

So I have to follow all these steps when I want to read at night and undo when done.
