The sky never ceases to amaze me. Be it peaceful blue sky, cloudy sky, rainbow in the sky, and sometimes the violet sky. How does the sky become violet all of a sudden? Well, according to scientists, the color of the sky depends on how shorter the wavelength of it then more light will scatter. If we remember ROYGBIV, it indicates that red having the highest longest wavelength and violet with shorter wavelength therefore B-I-V colors tend to take the most color of the skies. The blue sky appears because of all the blue light scattered. Also, there are times during sunset we can see the red sky appear. If we follow ROYGBIV and violet has the shorter wavelength, then shouldn't our sky be violet? The answer is yes and no. Yes, our sky really is violet but then no since our eyes perceived that violet sky appears as blue. So the violet sky is just a matter of right timing with the right particles in our atmosphere.
