If you are on windows you can use this awesome tool to have it globally: https://zerowidthjoiner.net/negativescreen https://zerowidthjoiner.net/negativescreen nice plus: inverted mode with correct colors (only brightness inverted) You could even write your own translation matrix. It's a bit tricky at first, but fun. e.g. true black and white without greys. For your own matrix this might help (but definitely another format :/ ): https://kazzkiq.github.io/svg-color-filter/ https://kazzkiq.github.io/svg-color-filter/ http://alistapart.com/article/finessing-fecolormatrix http://alistapart.com/article/finessing-fecolormatrix

If you are on macos you can do it globally and natively by going in the accessibility settings.

  Same goes for any recent Windows version (1709 or 1803?) - Settings -> Ease of Access -> Color filters.

    Shortcut Win + Ctrl + C. I've known a couple people accidentally press it and think their display is broken! Use it quite often for quick visibility testing.

  Check out Nocturne (originally from Blacktree, of QuickSilver fame). It even has a full red monochrome option (in case you need to finish that paper at 2 am but don't want to keep your roommates awake). I really wish Android and iOS had a full red monochrome night-vision mode. Short of that, for Android, you can switch to monochrome directly in Developer mode: https://www.trishtech.com/2016/02/how-to-turn-android-lollipop-screen-monochrome/ https://www.trishtech.com/2016/02/how-to-turn-android-lollip...

    iOS does have a red monochrome option! Settings > General > Accessibility > Display Accommodations > Color Filters > Color Tint Not the easiest to find, but it's there for people who need/want it.

      Not the same. Nocturne turns white black and black red. But have an upvote for the suggestion!
