What happens if you have multiple Slack workspaces to keep track of? Or, what if you want to customize your Slack channel to fit your business brand? You can use Slack’s theme customization tools to create Slack themes that perfectly fit using color and more.

Where to Find a New Slack Theme

Before you dive into creating a unique theme, you can find custom Slack themes ready to go online. You can either go to the Preferences section inside Slack to find a few themes to choose from or do a quick Google search to find several websites where Slack users can share their custom themes. Some of these websites include:

  • Sweet Themes are Made of These
  • SlackThemes.net
  • BirchTree

With each theme, you’ll see the hex values you need to customize your own Slack channel. You’ll use these hex values to add your new theme to your preferences.

How to Add a New Slack Theme

  • When you locate a theme you wish to use, select and copy the hex values.
  • On your desktop, open Slack and log-in as normal. From the workspace you wish to change, select the workspace name in the top left corner.
  • Select Preferences.
  • In the left-hand menu, Select Themes.
  • At the bottom of the page, under Colors, select Create a custom theme.
  • Working from the left to the right, paste your hex value codes into each box to create your custom theme.
  • As a quick shortcut, delete the hex value codes from the “copy and paste these values to share your custom theme with others” field, then paste your hex values just like you copied them and your theme will be complete.
  • Voila. Your Slack theme is complete.

How to Customize and Create Your Own Slack Theme

On your desktop, open Slack and log-in as normal. From the workspace you wish to change, select the workspace name in the top left corner.

Select Preferences.

In the left-hand menu, Select Themes.

How to Share Your Custom Theme

Want to share your new and customized theme with your co-workers or workspace members? You can do so easily using the hex values you now have listed as your theme.

Your Slack workspace is uniquely your own, and there are endless ways to customize your space to fit your needs. For example, you can choose to create a dark Slack theme for working late to keep your eyes from straining. You can also create multiple themes to fit each workspace, so you can easily choose between them in the sidebar.
