How to change the background color in SumatraPDF reader?

If you use dark theme for windows colors and want it used on SumatraPDF. Find SumatraPDF/SumatraPDF_settings.txt and one of the first lines UseSysColors can be changed from false to true.

"Go to 'Settings' > 'Advanced Options...' It will open SumatraPDF-settings.txt file in the text editor.
Then change the hex value of BackgroundColor option under FixedPageUI or any other corresponding *UI section.

"There's a command line option to invert colors:

sumatrapdf.exe -invert-colors

Basically for black-text-on-white it will produce white-text-on-black, while making other colors still readable just by inverting them also (in PDF-Xchange on contrary, if there are e.g. gray boxes, their contents might become unreadable afterwards).

Additionally, there's -set-color-range option which is more general:

sumatrapdf.exe -set-color-range 0x00dd00 0x000000

This will produce green text on black background and scale other colors appropriately.

"Unfortunately, I believe it's not possible.

The -bgcolor argument will only change the background color of the start-up screen."
