The color of Uranus is a blue-green color, and the color of Neptune is a bright azure blue. The reason this is the color of Uranus is due to its atmosphere and its ability to absorb different bands of light.
Uranusâ rings werenât discovered until 1977, because they are made out of material that is extremely dark. Half way through Uranusâ orbit (every 42 years), the angle between Uranus and Earth lines up in such a way so as to allow us to see Uranusâ rings edge-on from Earth. Figure 1: This infrared image of the dark side of the rings was taken by the Keck Observatory in 2007.
