GratiTuesday: The Colors of Fall

I have been enjoying the photos many bloggers have posted of their gorgeous autumn foliage. The rich reds, oranges, and yellows are truly spectacular and make me wish we had the same seasonal brilliance where we live. Except for a few liquid ambers dotting our neighborhood, our temperatures don’t get cold enough for most of the trees that produce the glorious fall displays.

Fortunately for us, even though we don’t have the blazing foliage colors enjoyed in colder climates, nature paints her brilliant fall hues on a different canvas. Rather than the reds, oranges, and yellows appearing in the trees, these colors are splashed across the sky.


There is, of course, a scientific reason why fall and winter sunrises and sunsets are so spectacular. As the days grow shorter, the angle of the sun is lower which means that the sunlight takes a longer path through the atmosphere. Since blue light has a shorter wavelength, it gets scattered by air molecules. Colors with longer wavelengths, such as reds and oranges, become more pronounced as they pass through the atmosphere.


Clouds also add to the beauty of sunrises and sunsets because they catch the red-orange rays of the sun and help reflect the colors. Cirrus and altocumulus clouds are especially conducive to spectacular displays because they are high enough not to be impacted by the dust and haze in the atmosphere.

But, enough science…

Fall’s colors are magnificent no matter how they are made or what canvas they appear on. Each time I am treated to the beauty of a dazzling sunrise or a vivid sunset, I am so grateful to be a witness to nature’s artistry. Because, to quote the great Dr. Seuss, “when you stop and look around, this life is pretty amazing”.
