How to Customize and Create Your Own Slack Theme

Can't find a theme you like that someone else created? You can easily create your own theme using Slack's built-in theme customization tools. All you have to do to get started is log into the Slack workspace you wish to customize.

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.

  1. In the upper left-hand corner, select the name of the workspace you wish to customize, then select Preferences.

    Selecting Preferences in Slack.
  2. In Preferences, select Themes. Here, you'll find a list of all the changes you can make to your theme on Slack.

    Each color represents a specific area of your sidebar. For example, "Column BG" is the background color for your entire sidebar.

  5. Once you've finished changing the colors of your sidebar, simply exit your preferences to save your work.

You can change or switch your theme at any time with Slack's easy to use customization features. Go ahead and experiment, seeing which color schemes work best for you.

How to Share Your Custom Theme

How to Customize Your Slack Icon

Once you have a theme that fits your business, brand, or personal needs perfectly, it's time to seal the deal with a matching Slack icon. Your Slack icon could be a wide range of things, including your business logo, a quirky photo of yourself, or a customized graphic. The sky's the limit here.

Only users who own their Slack workspace, are admins of the workspace, or are organization owners can change the workspace icon.

  1. Log into the Slack workspace you wish to customize the icon for. Alternatively, in the Slack app, select your workspace icon, then select Settings & administration > Customize <your workspace name>. This will open up the workspace in your browser.
