From your desktop, you can redecorate your Slack workspace at any time by choosing a new theme or customising your own. If you're a member of multiple workspaces, try selecting a different theme for each one to help you quickly tell them apart.

Choose a new theme

You can customise the appearance and functionality of your sidebar, plus the look of your workspace. 

Your new theme will appear wherever you open this workspace: desktop, web or mobile!

Note: The theme you choose will only be seen by you and is not visible to other members. Read on to learn about sharing your new theme!

Tip: in your sidebar preferences, you'll find accessible themes that some people with colour-blindness have found helpful.

Select custom colours

To select custom colours for your Slack theme, you can type in any 6-digit HTML colour value or click a colour swatch to choose from the colour picker.

Share a custom Slack theme

Here’s how to share your custom Slack theme:

From their desktop, team members can just click the Switch button to start using your theme.

Tip: When you paste any 6-digit colour value into Slack, we’ll display a small swatch for each colour. 🎨✨
