The last time that I was sitting at the tower it was New Years eve 2008, drinking Champagne, dodging Gendarmarie, and chatting with some lovely people from Dublin. The tower was bathed in a blue light with the circle of stars for the EU flag. As we watched, it turned from blue back to yellow. I never got a photo of it yellow, since I was rather drunk on Champagne and didn't want to have my camera out in those crowds. I now have finally managed photos of the yellow lights.
