After some more thought I took a different direction with that second background and made the color palette more consistent with the first one -- and the other four, for that matter:

I like not only the consistency, but the fact that it's darker, too. The crazy toxic green was a bit too much in and of itself -- and didn't looke like anything else in the game. Too bright and crazy.
