Change your Slack theme

To change the color of your workspace, choose a new theme, or create your own custom theme.

Tip: If you’d like a darker look for Slack, learn how to turn on dark mode from your preferences.

Choose a new theme

If you use multiple workspaces, try selecting a different theme for each one to help you quickly tell them apart. Your new theme will appear whenever you open that workspace, including on the desktop app, browser, and mobile app. 

1. From your desktop, click your profile picture in the top right.
2. Select Preferences.
3. Click Themes.
4. Below Colors, select a theme.

Note: When you have dark mode turned on, the existing options for sidebar themes will look different (and darker) than they do in light mode. Custom themes will look the same in light and dark mode.

Tip: In your Themes preferences, you'll find accessible themes that some people with color-blindness have found helpful.

Customize your theme

1. From your desktop, click your profile picture in the top right.
2. Select Preferences.
3. Click Themes.
4. Below Colors, click Create a custom theme. Enter any six-digit HTML color value, or click a color swatch to choose from the color picker.

Share a custom Slack theme

Your custom theme will only be visible to you, but you can share it with other coworkers by clicking the Copy button below Copy and paste these values to share your custom theme with others. Paste your theme into any channel or direct message and members can click the Switch sidebar theme button from their desktop to start using it.

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