Tony's answer was pretty funny, they are warm.
But yes, his second answer is correct...they are very bright white lights that allow the audience to see me occasionally. On the first tour, I was in the dark most of the show, I'm not vain about such things but for the fans' sake, thank jeebus they finally put some decent lights on me.
