      The dust and gas in the air cause the blue color of the sky.

      The sky is blue as that is the colour reflected as the light passes through the air

      Blue color scattered more than other colors because it travels as shorter and smaller waves. This is why we see a blue sky most of the time. You might like wot watch this video:
