The theme uses the Breadcrumbs NavXT plugin to display the breadcrumbs in the theme. If you are using an SEO plugin such as Yoast SEO or Rank Math SEO you do not need to install Breadcrumbs NavXT, but you can use the breadcrumbs feature of the SEO plugin.

The colors of the breadcrumbs can be changed under Appearance → Customize → Breadcrumbs, also the options to hide the breadcrumbs and alignment can be found there.
