For startup adding -invert-colors to the command line, it will invert the colors for the rendered document.īackground will change to dark, texts will change to bright gray however it will not invert a, say blue text to yellow, like MuPDF does. I don't think it can also invert all colors, but I do not have the latest release available right now to check. Hitting w in presentation mode, it changes background to white.
It is made by the same company which brought us Ghostscript.

I've tested it a few times in the past Just in case the OP doesn't really need to change the PDF document colors permanentlybut only wants a PDF viewer other than Acrobat that can do similarly change the displayed colors It can invert the displayed colors with the simple stroke of the i for any document while it is open. It is unreliable, because not every PDF viewer will honor that setting. It sets up a colortransfer function for the output PDF file. Finally, here is a rather unreliable way to accomplish the inverting of colors with the help of Ghostscript. But this will at the same time munch and make mincemeat of your nice vector PDFs, converting them into complete-raster image pages: convert nice. You can also achieve a permanent color change inverse colors quite easily with the help of ImageMagick. It will not work for pages or areas where the background is opaque white or color. Note, this will only change the background of these pages or those areas of pageswhere the original background is transparent, as most text-based PDFs are. Then apply it to your original PDF A4 : pdftk original. To create a PDF page A4 size which could serve as the gray background, you could use Ghostscript: gs -o gray. A black background would surely make it unreadable, because most text is black and would remain so. I've shortly considered to apply a gray-ish background to the PDF with the help of pdftk But this would probably make some or many PDFs unreadable. However, you might be able to achieve a similar thing by applying a suitable ICC color profile to the input PDF and produce, with the help of a very recent version of Ghostscript, a new output PDF from this. The PDF remains the same during and after viewing it. What you describe for Adobe Reader does not change the PDF file itself, it changes the way the application renders the pages by inverting colors, or similar. Because in the general case, you'll have to change all colors of the PDF pages, not just the background alone, so you can still have some contrast and color differences.
