    Somewhat related: I really like f.lux's "Darkroom" feature. Although I no longer use the app to reduce blue light after the advent of macOS's Night Shift, Darkroom mode tints the screen completely red (like a red version of Color Filters). It's great for working during the wee hours. https://justgetflux.com/. - Source: Hacker News / 12 months ago

As soon as you go above "slight" (can't remember the numbers, I'm not a frequent windows user and don't have one handy to check) it gets a sickly yellow taint.
