What gas gives Uranus a bluish color?

Answer 1

Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's atmosphere absorbs the red light spectrum from the sun and reflects the blue light into space.

This is why Neptune appears to be blue.

The atmosphere of Uranus is composed primarily of hydrogen and helium, with a small amount of methane and traces of ammonia. Uranus gets its blue-green color from methane gas also. Sunlight is reflected from Uranus' cloud tops, which are under the layer of methane gas. As the reflected sunlight passes back through this layer, the methane gas absorbs the red spectrum of the light, allowing the blue spectrum to pass through, resulting in the blue-green color that we see.
