A Rainy Autumn Afternoon

Why is it that a rainy day seems to bring out all the fall colors ? The wet sky today had such a palette of colors -- indigo, magenta, violet -- as the sun sank in the west.  The cottonwoods seem to find the slightest breeze to wave their golden leaves, and they stand in stark contrast to the stalwart spruce trees.  How privileged I feel to have spent the last of the day's light with a paintbrush in my hand.
