You can find customization options for your Catalog page when you access the Preferences tab on the Website menu. Changes made here don't affect your home page theme.

For instance, you can choose how your users will view your content. You can decide which Playlist Position is best, and what Featured Category would be best to display, whether to display the Library and Continue Watching categories on the Catalog and the Mark as Watched feature on the Programs page.

Additionally, you can locate the Theme Customization by navigating to Website, then opening Customize in the Themes tab.

Click the Theme Customization option.

You can find options to set a Primary Color for your site, change the Color Scheme between Light and Dark, change the Logo and Favicon, select your Fonts, change the Login Page Banner and select the Theme Homepage.
