Slack is introducing a new dark mode for desktop versions of its workplace chat app. The new dark mode for desktop option will be available across all platforms today, allowing Windows, macOS, and Linux users to switch away from the traditional light theme that’s always been available on Slack.

Slack is enabling dark mode variants of all existing sidebar themes and adding its own “Nocturne” dark mode theme that can be set on both desktop and mobile. The desktop dark mode comes months after the same feature appeared on iOS and Android versions of Slack earlier this year.

“Dark Mode is an important feature for lots of people,” explains George Zamfir, an accessibility product manager at Slack. “It’s helpful for working at night or in low-light, and we know many need it for accessibility reasons like visual impairments, migraines or other visual disorders.”

You’ll need to update or relaunch your Slack desktop app to find the new dark mode options in the themes part of settings.
