 Colorful Clouds Observed at Sunset

   Summary Author:  Spyros Antonopoulos

   The photo above showing colorful cloud colors at sunset was taken near
   Chalkeia, Greece. Of course, the  color of a cloud depends primarily
   upon the color of the light it receives. When the  Sun is low in the
   sky, because the  path the Sun's rays take across the sky is longer
   than if they were coming from straight above (zenith), the shorter
   wavelength colors (greens and blues) tend to be scattered from our
   view. This leaves the red, yellow and orange colors to paint any clouds
   lying in the track of the Sun's lingering rays. The closer the Sun is
   to the horizon, the longer the path-length of its rays, and thus the
   redder the color. Photo taken on July 10, 2022.
