Drupal 6: Hot new themes
by Robert Douglass
This video highlights the new theming features of Drupal 6. The themes, Pixture, Wabi, and Twilight, are the work of Hide Ito (Pixture), and utilize not only the Farbtastic color picker, but also the ability to adjust the width of the layout, and in the case of Twilight, a configurable header silhouette.
UPDATE: The process of configuring recolorable themes is described very well at Pixture Studios.
