Theming Slack using a message

The Slack (desktop) client allows you to create your own themes. But did you know that you can also set the theme via a message. Simply send a message with the contents being 8 comma separated hex codes. You don't have to send the message to anybody either - Just send it to yourself!

#DCDCDC,#ED6970,#ED6970,#FFFFFF,#FFFFFF,#291d1f,#1c7c5a,#3a4a8ff

These stand for the following elements:

  • Sidebar & top bar background
  • ????
  • Highlighted channel background
  • Highlighted channel text
  • Highlighted channel background (hover)
  • sidebar text
  • Online indicators
  • Message indicator

As soon as you send this to yourself a little button will appear giving you the ability to trigger a theme change.
