Baby blue at cold dusk

My bus was rerouted this afternoon because of some street fair, and I had to walk home a different way. What happened then was this --



Isn't that beautiful? The cold with leaves crunching underfoot and the day turning to dusk made this blue piercing, and not just visually (not sure how to explain). It looks like a Globe Roll but I can't be sure. All I'm sure of is that I've gone back and re-looked at this picture a few times tonight, which hasn't happened with a bike photo in a long while.
