Because Uranus was with a person from the movie Avatar
Uranus' atmosphere is primarily composed of methane and ammonia, which give it its blue-green colour.
The clouds have a little bit of a blue/green colour but what really makes that colour is the methane crystals in the upper atmosphere of Uranus gives it that blue/green appearance
Uranus or Neptune i think.... :P
pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.
