Reading: White Text/Black Background

[RMD68]

I read a lot of online material, but only a few sources use white text on a black background. I understand why the normal scheme is used for printed material so I'm not surprised that people were accustomed to reading black on white, but I find it's a lot easier to read white text on a black background when reading dense material on a computer screen.

I know I can invert the colors in setting, but is there any other way to just change the background without changing the entire color scale?

Thanks!
