Color fixes.

I made several changes to behavior here, including decoupling colors from panels. We're now just switching back and forth between green and blue. (The *dispatches* panel retains some purple in an image element... whatever. If it looks terrible I can rotate that to a different color in Pixelmator.)

I banged my head against trying to get a local test copy of the site running on my machine for about thirty seconds, but I have to move on today; that means this was developed in the blind – @topherfangio could you run this once before merging & publishing just to make sure I didn't bork everything?
