Red Rainbow

After the intense fire of the sunrise I showed you yesterday died down, I rounded the corner and was awe struck by this sight to the west. Red rainbows are a rare treat, as they can only happen when the sunlight travels long paths through our lower atmosphere, where they are scattered by air and dust molecules. The shorter wavelengths of blue and green are scattered the most,  leaving the remaining light richer in reds and yellows. Due to the special circumstances needed for the production of a red rainbow, they  remain an illusive treat.
