I had the opportunity to see Spamalot at the Pantagas theatre in Hollywood today. Unfortunately, I was unable to take a photograph. I noticed that the lighting altered  drastically with the mood of the play. When the king began to speak about an idea, very far-fetched, the lighting changed from a light, somewhat naturalistic lighting to a purple haze. The purple let the audience understand that the ideas he was speaking of were not of what was happening in the moment. I thoroughly enjoyed how the quick, drastic change of light let the audience understand a concept without the use of words. It enhanced the idea.
