I'm looking for a web based CSS picker
Part of the myKB.com application I work on has a styles screen. This lets users define certain styles that get used in the application css, so they can change the look and feel of their knowledge base application. What we have now for an interface sticks.

Last week (or two) I blogged about finding a color picker, that makes picking HTML colors much easier than actually typing int eh HEX color code. What we have is effective, but it requires that the end user know something about CSS, which means they call in and our support does it for them, because no one in the real world knows CSS, and why should they have to? Can anyone recommend a web based CSS picker (hopefully an ASP.NET server control) that resembles the common windows UI for picking styles?

It doesn't have to be super advanced, but he more options the better.
