I know that these fall leaves may look vibrant, but overall, the fall foliage in Atlanta seemed to be duller this year and spectacular specimens were harder to find. Colleagues have told me that lots of rain can do that to the colors.
I noticed that many of the leaves seemed to be more opaque and they blocked the sun’s rays more. If the sun can’t get through the leaves, the color will not show as vibrantly. I could be wrong, but that’s what my eyes were seeing.
