Orange in Colorado

We went for a hike in the mountains on a recent Saturday. The leaves were nearing the end of their color changing.

I lived for 5 years in Massachusetts, in younger days. The color of fall leaves there covers a broader range than Colorado's. (You probalby already know that - people travel from far and wide to New England, just to see the leaves in the fall.) For some reason, yellow is the color of fall in Colorado. I was surprised to see this lone orange leaf.
