To get the dark mode on Slack, you need to update or relaunch your Slack app. Next click on your Company name on the left sidebar, go to Settings, Preferences, and Themes to find the new dark mode option. If you are like me who use Slack on All-in-One Messenger apps like Station or Web, you can enable Dark mode from the same settings.
The dark mode works everywhere including the sidebar, within the chats, as well as in the settings, allowing users to turn their screens black to make messages easier on the eyes. If you are wondering, Dark mode has already arrived for mobile apps, which you can enable, by going to tapping on the Overflow Menu > Settings and Under General, tap Dark Mode.
