Last week, we had to blog about our knowledge about the sky's blue appearance. This time, we have to give an exact answer. So here it is: the sky is blue because the blue wavelength from the sun is being scattered by the atmosphere more than any other color wavelength. This means that the blue wavelength is the only one that appears the most. So it doesn't mean it's the only color. 
          The sky is blue because it is the only color that is visible to us. It is combined with other lights in white light, such as red, orange, yellow, green, violet, and indigo. Blue is the only color that is able to be scattered the most and visible to our eyes. The further you go into space, the sky does not remain blue. Imagine if the sky was the color of all the different colors in the rainbow!
