It does need some colour, and since I couldn't get any of our custom images working I did up a quick test colour scheme, which is "test 1" on the drop-down menu on the bottom left of every page. It looks like if you select it once, it stays like that until you select something else, even when you come back later.
It isn't anything fancy, and won't be permanent (I can't even set it as the default colour scheme), but for those who are getting sore eyes looking at all of the white, check it out, until the more permanent scheme is done.
