Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.
Note: MAYO 7.x-2.0 released today which is a responsive mobile first HTML5 version. Check the release notes and project Documentation.
MAYO theme's name is taken from a phrase "MAke Your Own" and "MAYOnnaise" which I love ;-). As the name describes itself, MAYO is developed to be a theme that provides users easy way to customize and create a theme they like.
MAYO is developed based on the experience with PIXTURE theme. However, it takes full advantage of Drupal 7's color module and advanced theme settings. MAYO is simple but flexible. You can customize the look of your MAYO theme easily from theme settings page. It does not require you to have the good knowledge of CSS, HTML and PHP.
What can be customized from the theme settings page?
Color of most of the theme elements (base, page, header, sidebar, node, footer). In many cases, you can specify text color, link color, background color and border colors of each element.
Base font and heading font type (either Serif or Sans-serif) and base font size.
Page layout options such as width of the site (fixed width layout or liquid layout), margins, sidebar layout and width, etc.
Styles such as menubar styles and round corner for node/sidebar block.
Detail layout of header area contents (logo, site name, slogan, search engine box)
You can easily upload and add your own image as the background of the header area. (You can use both background image and logo at the same time).

Xtheme is a light Sass and nodeJs based Drupal starter theme. This theme differentiate it's self by it simplicity and structure. It does not incorporate a grant list a features but rather embodies a frontend workflow. I have not found on drupal any theme that does this, many of the existing theme's are bloated with features and drupal overwrites. Xtheme does not want to rewrite drupal output, just makes it easier to develop a theme for drupal in a structured way.
