The sky is alive with colors all during the day and the clouds that decorate the sky just make it more interesting.
Typically we think of red with a sunset, but it depends on just when you see it and other factors like the amount of dust and smog in the atmosphere as well as clouds. This picture was inspired by a beautiful picture taken by P-M Hedén and can be seen, along with other beautiful images at Clearskies in the Noctilucent Clouds Gallery. (Noctilucent clouds are clouds at very high altitude made of ice crystals that can be seen late into the twilight hours.)
As usual, you can check out more wallpapers at the gallery page.
Till next time,
