This type of weather is also the most favorable for a spectacular show of autumn colors, making this season of the year still more delightful.

Why Leaves Change Color
http://www.na.fs.fed.us/spfo/pubs/misc/leaves/leaves.htm
f you are lucky, you live in one of those parts of the world where Nature has one last fling before settling down into winter's sleep. In those lucky places, as days shorten and temperatures become crisp, the quiet green palette of summer foliage is transformed into the vivid autumn palette of reds, oranges, golds, and browns before the leaves fall off the trees. On special years, the colors are truly breathtaking.
