Before the sun rises in the morning the first sun emits a beam that absorbs into the clouds, so the clouds appear red in the sharp morning sun.
Sunlight that enters the clouds displays various shapes but the scene will not last long because, the sun will soon rush upward after the phenomenon of red clouds and red clouds will soon disappear.
Red clouds are only visible in the morning and when the sun begins to fall, this scene is sometimes invisible because of the thick cloud covering it.
