Methane.
Uranus has a blue-green color as does Neptune
No. Uranus and Neptune owe their blue color primarily to the presence of methane.
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.
