Theme and branding

The theme for Drupal.org is called Bluecheese. It has two parts. Public part is located in Drupal.org repository. Private part, contains brand elements and is located in the private internal repository in order to preserve Drupal.org's 'brand' identity.

Public version of Bluecheese is not intended and supported for download and use outside of Drupal.org. It it there only to make it easier for community members to improve Drupal.org.

The Drupal wordmark was custom designed by Mark Boulton Design.
