Denver's City and County Building is often lit in different colors according to a monthly theme. Pink for breast cancer awareness, red for heart disease. Last year in October it was purple for the Rockies, who were in the World Series. (So nice to have a team with an attractive jersey color!)
This November it's been purple again. Not for the woeful Rockies, so I was puzzled, until it occurred to me yesterday: Maybe because we're a purple state!
But tonight it wasn't lit up in blue, so that theory's blown.
