why Neptune and Uranus appear different in colours?

In News 
  • Neptune and Uranus have much in common — they have similar masses, sizes, and atmospheric compositions — yet their appearances are in different shades of blue.
  • At visible wavelengths, Neptune is a rich, deep azure hue, while Uranus is a distinctly pale shade of cyan.
Reasons 
  • Neptune is a rich, deep azure colour at visible wavelengths, while Uranus is a notably light shade of blue.
  • Astronomers have now found the explanation for this.
  • The cloud around Uranus is thicker than around Neptune, which explains why.
  • Uranus seems lighter in tone than Neptune because of its lethargic, sluggish atmosphere.
  • If there was no haze in Neptune’s and Uranus’ atmospheres, the blue light scattered in their atmospheres would make both appear nearly identically blue.
