On the return trip from a backwoods hike I noticed a section of the SSE sky that had brilliant colors of purple, red, aqua, and different shades of blue. I also noticed different shades of blue ranging from very light to very dark throughout the rest of the sky. I could not see all that without my sun glasses because it was just East of the sun. I hurried home, grabbed my camera and an ND filter to try to capture those colors but I was too late, they had gone away. The sky was then somewhat boring in comparison, so I shot the clouds that were near the sun anyway.
