Is there a pdf reader allowing me to change background color of (arXiv) pdfs?

Its quite common that one wishes or has to read lots of PDF files which are intended to be printed, but since one would read them only once, and one wishes to save some trees, one reads them on Acrobat Reader, evince, xpdf or whatever your choice.

It would be an advantage to be able to control the background's color. Instead of black text on white background, I'd like to have a gray background. By googling I just get the inversion of colors as suggestion – which is sometimes even worse for the eyes.

Is there a pdf reader allowing me to change background color (without changing the color of the text)?

Edit: The first comment below suggests it depends on the file. Therefore I added to the title arXiv's.

You can do this in Okular if you don't mind pulling in kde dependencies.

sudo apt-get install okular

The option is found in Settings/Configure Okular.../Accessibility by checking Change colors then Color mode: Change Paper Color and select a color in the swatch below.

You can also select Color mode: Change dark light color and choose your favorite dark and light colors. An answer below (for Zathura suggested #dcdccc for dark and #1f1f1f for light, which are quite nice.

To use this as a shortcut Right click toolbar -> configure toolbar -> main tool bar <okular part> -> toggle change color.

Works with several pdf files I have from arxiv, but perhaps unsurprisingly, doesn't work with pdf files that are simply scans of pages.
