Atmospheric perspective: The Sky is Blue because it is Black

  1. Moisture — act like very thin fog — reduces contrast
  2. Prismatic effect of moisture and dust in the air making the air act as a turbid medium. A turbid medium acts like a prism. So if light is falling on an object that is more black, it will shift to the violet/blue end of the spectrum, but if it is falling on an object that is more white, it will shift to to the red/orange/yellow end of the spectrum.
