As this political junkie is watching the results, they showed a preview of the room where McCain is giving his speech. It appears that, at least for tonight, all of his signs/backdrops are GREEN.
Has he ceded his normal campaign colors to Obama? From a marketing perspective, (my first major was marketing) I find it interesting that he is pivoting to a new color. Trying to prove he can change, perhaps?
If anyone has a screen grab, I'll go back and add it.
