Gnome Invert Colors
Inverts the color of individual windows so they are hue-preserved. Default shortcut is Super+I Extension Homepage https://github.com/jackkenney/gnome. I dislike that most websites use a black font on white background for their sites, as it gets too tiresome for me to read.
Back in the days of 11.04, using Gnome2 with compiz, there actually was a Negative feature that could negate the content of any window, making the background black and the font white. Much easier on the eyes for me. Yet since 11.10, using gnome shell with mutter, I have no.

GNOME shell extension for inverting window colors in hue preserving manner. Effectively an automatic dark theme for GNOME windows. - JackKenney/gnome.
I've looked at doing this via a colour scheme (high contrast inverted) in Gnome3 without success - with liferea and icedove, menus and sidebars had the inverted color scheme but the parts where actual text is displayed where still black on white. Maybe there's a better scheme for this purpose? the xrandr-invert hack shows a noticable delay between un-inversion and inversion when opening or closing overview mode. This is solved by using gnome 32+ and/or disabling/not having xrandr.

To swap black for white, white for black, and so on, press the menu button in the top. Inverting colors is extremely useful. For example, say you have dark mode and you open some PDF with white pages, you can simply invert the colors to make it black with white text.
I use an extension called "True Color Invert" for this, where by pressing Win + I, it inverts the colors for the current window, which is perfect and exactly what i. Invert color the whole Gnome Desktop Environment for reading purposes. This extention use xcalib program for inverting the color, so you need to install xcalib first (in debian-based ditro you can use 'sudo apt-get install xcalib').

I use it quite frequently. It's great that it can invert colors of a single window. Works well on GNOME 3.32.
Thanks!
