So, what is night-mode?  It is a mode for changing the color temperature of computer screens to be ‘warmer’ (more red-tones, less blue tones).  Why?  The strong blue tones (and whites) from most computer screens help trick your mind into thinking it is still day, and therefor you need to be awake.

I have been trying to enable night mode on all the things for a while now.  For my android phone, I use twilight for Android (IOS has something built in now), Solus Linux added it in the most recent release, Gnome has it in the later releases, and under i3, I use xflux.

However, I could not find anything for the Chromebooks….until now! 9to5Google.com has a story about the feature coming soon to ChromeOS, but they claim that you need to be on the very latest development branch called ‘Canary’.  I tend to run on the Developers branch, and did not want to switch.  I did a bit of digging, and found this reddit thread which has the feature flag to set:

chrome://flags/#ash-enable-night-light

Normal warnings, this can lead to breakage of your system.

I have enabled it, and it is looking good so far!
