Use dark mode in Slack

Dark mode helps make working in Slack easier on your eyes by using a darker, higher-contrast colour theme. You can turn on dark mode from your Slack preferences, or sync dark mode in Slack with your operating system (OS) settings on certain devices.

Note: This preference is device-specific, so adjusting dark mode on the desktop app won’t sync with Slack on the browser or mobile app.

Android

  1. Click your profile picture in the top right.
