*nodnod* I'd be all about some kind of user-cookie that kept track of a handful of color settings. Then we could have the current three (or three and a half...) basic layouts for form and just slap on an extra style sheet to define colors.

Actually, that might work as both stopgap and something that will lend itself to eventual overhaul of the templates--the user-selected colors could just go into the last site style sheet in line with !important tacked on to each color, and that would do it fine as things stand.

...except with Celerity, which uses images to produce the trailing lines. Hmm. Maybe any user-selected colors applied to Celerity could trigger the inclusion of a few lines of background-image:none to take the images out.
