    It’s theoretically easy for a PDF reader to invert colors, but this seems to be a most uncommon option.

    zathura does that!

      It’s theoretically easy for a PDF reader to invert colors, but this seems to be a most uncommon option.

      Two other PDF readers I know of that support this are MuPDF (press i) and Evince (press ^I). I use this feature quite frequently.

        oh, sweet, never considered it before.

        1. 1

          Thanks for pointing out zathura, I’ve had a hard time finding a pdf viewer that I like and this one so far is quite pleasant!

          I recently switched to light backgrounds everywhere and an extreme redshift/sct setup (2000°K on the low end). Given that I have a terrible old screen on my laptop, this is the optimal solution for situations when I have to use a strongly dimmed backlight. And another, quite unexpected, effect is that even at night, I prefer a white screen with a strong redshift and slightly dimmed backlight to any other option. This might be connected to the fact that I find most dark color schemes to be less versatile and mostly way too jarring when it comes to contrast.

            This is what I do myself; agreed on all points. There have been studies composed on the subject over text and background color - here is one, for example.

            You might also try “Redscreen - Night Vision Filter for Linux”, which is a tiny script I wrote around xcalib a few years ago.

            …and good on ya, Ted, for being stubborn and running a self signed cert. I ran my sites with one too for many years until LetsEncrypt came along.

              Website appears to use self-signed cert?

                  Those links are, of course, not very helpful. =)

                  The discussion on lobste.rs has some discussion of it that may provide clarity or edification.

                  1. 2

                    Awesome, thank you both for those links.

                    This is an area I’ve been working in for quite some time, so it really excites me when I see people experimenting like this. Awesomeness! :D

                Some months ago I’ve also wondered about the same topic and compiled it here: https://venam.nixers.net/blog/unix/2017/06/04/why-green-on-black.html

                  The website is broken.

                    Takes a while to get used to but this has helped me several times: https://github.com/adrieng/xrandr-nightmode I’m not running it every night though.

                    1. 1

                      See, it’s stuff like this that makes me feel better about making a poor imitation of jwz’s site for myself.

                      The choice of sans-serif and non-blue seems to be working. :)

                      1. 1

                        On Firefox I am quite happy with Dark Background and Light Text. Works on FF for Android, too!

                        There are three different processing modes: simple CSS, stylesheet processor, and invert. Every now and then I need to switch modes to correctly process a webpage. It’s very rare that none of them work.

                        You can also choose your own palette, if you want to do a color scheme like solarized dark.

                        1. 1

                          This is something I battle with all the time.. I go from outside to nighttime-inside all the time.. typically inverting the XTerm stuff with the middle click menu has been sufficient -but I really want something that works across all the window types!

                          1. 1

                            I’ve found Dark Reader to be very helpful and rarely broken.

                            1. 1

                              hmm, just tried it and it inverted the already dark Ars Technica into a bright color scheme. so I could switch Ars back, or disable the extension, etc., but it feels kind of silly. But I’ll consider it some more.

                            2. 1

                              If you launch SumatraPDF with the option ‘-invert-colors’ it will invert the colors of any PDF it opens
