Color Garden

Color Garden is a free theme released on Museum Themes under the GPLv3. This theme is jam-packed with features, from WordPress 3.0 functionality to Twitter integration. Color Garden uses WP3.0′s custom header option, and comes with 4 unique headers that accent the 4 color palette options available on the theme options page. We’ve also built in custom menus, custom backgrounds, and post thumbnails, hitting all the bases for cutting-edge WordPress functionality. If you use Twitter, we’ve got you covered there, too, integrating Twitter’s new Tweet button into our existing social sharing block on single post pages and providing options to display your latest tweets in the sidebar or the footer. The footer and sidebar are completely widgetized, and the footer has three distinct columns to add widgets. If that wasn’t enough, we’ve embedded a custom typeface in the header using CSS font-face. Each color palette has its own unique stylesheet, so you can easily use this theme as a framework or build child themes (or skins) for it.

Ex Libris

Ex Libris was designed for writers and typophiles. Lacking fancy graphical bells and whistles, we focused our attention, instead, on making your content readable with full typographic control. Ex Libris features a unique approach to choosing the typography for your site. Rather than relying on the tired basic web fonts, we’ve embedded the gorgeous free fonts from font foundry exljbris, giving you freedom to style your site with access to full font families and unique typefaces, while maintaining a consistent visual style. We’ve also built the theme with a unique, optional home page layout (Magazine Style, pictured above), and kept an uncluttered approach to page layouts.

If you’re a writer, if you love minimalism, clean design and unique typography, Ex Libris was made for you. Literally.
