Nebraska’s Blue State Capitol?

Yesterday I was driving back to campus from Jones Coffee house where I helped photo club hang our exhibition (Photos coming soon). I noticed that the state capitol building had blue light shining on it from all 4 sides. I though this was cool so I stopped and snapped a few photos. These were taken hand held with my Fuji F30 P&S while leaning against as lamp post. Does anyone know why it was blue last night?



The pictures below are of the capitol during a evening when it is normally lit. I took these in the summer of 2007 I believe. They may have already been posted here but they are worthy of being posted again.
