Dark colored rings
have been detected around the blue planet, but are much less than those of Saturn. When these rings were discovered, it was
thought that they might not be complete, but this was disproved by Voyager 2. Neptune also has winds of hydrogen, helium,
and methane. That gives the planet its blue appearence. It had in its southern hemisphere a Great Dark Spot comparable to
Jupiter's Great Red Spot.
