I guess this means: Methane gives which planet its distinctive blue-green color? Methane gives Neptune its distinctive blue-green color. I'm not so sure about that. I think Uranus is that color, but Neptune is more blue than blue-green. You read different things in different books though. Neptune has Methane in its atmosphere too.
No. Uranus and Neptune owe their blue color primarily to the presence of methane.
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.
Earth can be considered somewhat greenish, especially in land areas thick with vegetation and seas filled with algae. But the planet you're likely thinking of is Uranus, whose atmosphere (as observed by Voyager 2, et. al.) appears to be a pale greenish-blue.
Earth is often called the "Blue Planet". Its surface is mostly covered in water (around 71%). Neptune appears blue because of methane gas in its atmosphere. Uranus is also blue, although the color is lighter (closer to aquamarine).
The blueish color of Uranus is from the presence of Methane in its upper atmosphere. Also, it is blue - green from the methane in the core of Uranus.
Methane gas gives the planets Neptune and Uranus the blue colour.

Because in the atmosphere , there is a gas called methane and it gives the planets their blue color.

methane Methane, which gives it it's blue color, hydrogen, and helium. ~Alex
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 has a blue-green color as does Neptune

Uranus.

Both Uranus and Neptune do, giving them a blue colour (bluish green for Uranus).
