I've been using Slack for a long time. Because I have multiple clients that require it for collaboration, I'm frequently switching between workspaces -- which means it can be hard to distinguish which team I'm dealing with.

I work very quickly, so I need to know which client I'm talking to at a glance: I depend on visuals to clue me in on who I'm about to chat with. Fortunately, Slack has a built-in feature to make this easier: custom themes.

The feature lets you create a color palette of your own, or opt for Slack to create one for you. You can also add a window gradient for an artistic look.

To start, you'll need a valid Slack account and the Slack desktop app. While you cannot create a custom theme in the mobile version of the app, when you apply a custom theme in the desktop app, it will appear in the mobile version.

How to organize your Slack workspaces with custom themes

Once you've finished customizing your theme, close the Preferences window. You'll be prompted to save the change.

Your Slack workspace will follow your new theme. You can then go to your other workspaces and create themes that are different from the one you just designed. I hope this helps you make Slack more efficient and effective for your workflow.
