Chrome OS may finally be getting a dark mode, but so far it’s only been spotted in its experimental Canary channel. So far, the Chrome OS has only been seen in its Canary channel.

Canary can only be accessed from Chromebooks switched into a special developer mode – not to be confused with the Chrome OS developer channel.

To activate dark mode on your Chromebook, you need to have the Canary channel installed. You just open Chrome and type in Chrome: //flags/ # enable-webui-dark-mode into the URL bar.

Android Central says the dark mode has some bugs, but notes it seems to apply across the UI, not just as darker backgrounds.

Google has rolled out dark mode versions for its Gmail, Google Calendar, Google fit, and its mobile app over the last several months. Both iOS and Android both began supporting dark mode at the system level last year.
