It seems the phrase “sky blue pink” is out of style these days. Don’t know why. Too bad.
“Red, orange and pink clouds occur almost entirely at sunrise/sunset and are the result of the scattering of sunlight by the atmosphere. The clouds are not that color; they are reflecting the long (and unscattered) rays of sunlight which are predominant at those hours.”
