Not color.module compatible

The CSS is for the garland theme and doesn't look clean with other themes or colorized garland theme. See the attached screenshot.

As long as this is a prototyping module it's not too big an issue, but to be applicable to core we need to write a patch for core default.css or system.css with generic theming, add to garland's style.css, make that color.module compatible, and add to write patches for other core modules.
