Theming Slack using a message

Feb 15, 2019

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!

These stand for the following elements:

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