Themes are used to change the appearance of your Confluence site or spaces. You can download and install other themes from the Atlassian Marketplace.

Once you've installed a theme, you can apply it to the whole site or to individual spaces.

To see the themes installed in your site, go to

(Settings)

in the Confluence navigation > Themes. You'll see a list of all the themes installed in your site.

When a new space is created, the theme applied to the whole site will be applied by default to the new space. To change colors for individual spaces, you'll need to download a theming add-on from the Atlassian Marketplace.
