The day did seem that blue.
This, if you've spent several years in a cave or something, is the pyramid entrance to the Louvre. The building was once a French royal palace. but it's been in the possession of The People for a long, long time now.
It's not a great shot because the crummy camera I had just wasn't up to the challenge. The colors on the original JPEG were a bit wonky, and I don't have the heart to bang my head on it again. Maybe one day.
