Interesting, they have the lights all around the left side of the studio back to light blue/white. The lights that line the LCD screens at the big desk are also the same color (they're normally dark blue during Weather Center), and the green screen is turned facing the desk so that it's in the two-person shot they used going to break.
I wonder why they use blue lights on that wall when at the little desk and for the First Outlook desk configuration; I guess maybe the red lights don't look good up close?
