Neptune's atmosphere is made up of helium, hydrogen and methane.
Neptune appears blue because the upper methane atmosphere absorbs the red spectrum from the light and reflects back the blue light spectrum from the sun back into space. Giving the impression that it's a blue planet.
Neptune appears blue due to the methane gasses in the atmosphere absorbing the red light spectrum and reflecting the blue light spectrum back into space.
Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's upper atmosphere absorbs the red light from the sun but reflects the blue light from the sun back into space. This is why Neptune appears blue.
Uranus and Neptune appear blue due to methane gasses. Earth is also mostly blue due to vast oceans.
Earth is the only planet in our solar system that appears blue-green from space due to the presence of water and vegetation.

Neptune
Neptune appears to be a Royal Blue colour. It is a freezing gas giant. It is also extremely windy and stormy. The colour is caused by the methane in the atmosphere absorbing the red light spectrum and reflecting the blue light spectrum back into space, giving the impression that Neptune is blue. However, whether Neptune really is blue or whether the blue is just an illusion caused by the reflected spectrum is wide open for debate.
Neptune's color appears blue due to the presence of methane in its atmosphere, which absorbs red light and reflects blue light. Its color may vary slightly depending on factors like cloud cover and atmospheric conditions, but it generally appears blue from space.
