In addition to modify the settings file, Is there another better way?

There is no single background in SumatraPDF there are many so for

images and presentations the "background" is pure "black" mainly by necessity to show lighter foreground objects
- the User Interface has a background setting MainWindowBackground = #80fff200 that used to be Watchman Yellow but so got many complaints and is now neutered so unchanged its not the correct value its a more neutral colour

In the Fixed UI you can over-ride the Main Windows Background colour by using GradientColors = #0000FF #FF0000 this will change the colour around the paper zone

All the above have no need for a "quick change"

For viewing transparencies and negatives you need a fast method to toggle inversion so to Instant Invert Interface colours there is the I key
