I like gpEasy cms' quick and easy interface : powered by jquery interactivity, gpeasy is full text cms that works without a database. It is in fact a set of includes that can be administered via privilege based backend that implements FCKEditor. Below is a sample of the drag and drop interface for pages ordering, a must.
Drupal's new version (7) is in development and it features many improvements, most of them modules developped within the community. One of them is the Garland theme that allows customization of colors, enabling all theme variations including header shades. Another theme that works like that is the CTI flex theme, based on Zen, only available for drupal 6 as of now.
