How to change the background color. I would like to change it to something easier to read, is there an option to change this anywhere?

Best Answer

If you run SumatraPDF with the command-line option -bg-color 0xffff99 it will launch SumatraPDF with the new background color, and save the background color as your default.

The 0xffff99 part is the hex code for a lighter yellow.

Alternatively, the following command line option can be used:

  • -invert-colors

    Swaps text and background color for most documents
