the civil twilight '' starts at sunset and continues until the brightest stars are first seen. It's
the common legal meaning of twilight, as there is still light for many outside "civil" activities
and most streetlights haven't been turned on. Technically it ends when the sun is 6 degrees
below the horizon, or about 25-30 minutes after sunset for temperate latitudes most times of the year.''
During the twilight , the clouds display beautiful colors from gray-blue to pink and purple.
