Why does Neptune has blue color?

Answer 1

The planet Neptune looks blue because of the methane gas in the atmosphere.

The methane absorbs the red spectrum from the dim sunlight that reaches Neptune and reflects the blue spectrum. This gives the impression to us that Neptune is a blue planet.

Whether Neptune really is blue or whether it's just an illusion caused entirely by reflected light is open for debate.

Answer 2

Neptune's blue color is due to the presence of methane in its atmosphere. Methane absorbs red light and reflects blue light, giving the planet its distinct blue hue. The exact reason for the amount of methane on Neptune compared to other gas giants is still under study.
