At sunrise and sunset rays must pass through a thick layer of fresh air to shine on the sky around the horizon. When going through that thick layer of gas, the violet rays and indigo rays are short wavelengths, scattered very weakly so that the sky is not much, the rest are only red, orange, yellow rays are the rays Long steps. These rays are scattered by the molecules of gas, steam and dust in the horizon, making us see bright clouds early, afternoon clouds.

The more steam and dust, the more beautiful the cloud. The clouds in the sky are also colorful.

On August 23, 1883, the island of Krakatoa of Indonesia experienced an intense volcanic eruption, volcanic ash must reach 18 billion cubic feet, the dust flew to 7-8 ten thousand meters, covering the sky for a long time. That year, everywhere in the world saw red and bright red clouds, people called "blood trying ".
