Helium makes up most of Neptunes atmosphere, and some within Uranus. It is this helium that gives Neptune it's blue hue.
Gas
The planet you are referring to is likely Uranus. Its atmosphere consists of hydrogen, helium, and methane. Uranus is known for its distinctive blue-green color, which is due to the presence of methane gas in its atmosphere.
Uranus and Neptune are both gas giants, but Neptune appears darker than Uranus because of its deeper blue coloration. This difference is primarily due to the presence of methane in Neptune's atmosphere, which absorbs red light, making the planet appear darker overall.
Uranus is tilted on its side, while Neptune rotates on a more typical axis. Uranus has a blue-green color due to the presence of methane in its atmosphere, while Neptune has a deep blue color from the absorption of red light by methane in its atmosphere. Additionally, Uranus has a more bland appearance with fewer visible features compared to Neptune's dynamic weather patterns and prominent dark spot known as the Great Dark Spot.
Neptune and Uranus both have high concentrations of methane in their atmospheres.

hydrogen,helium, and methane
Because of the methane in their atmosphere.
Gas
Both Uranus and Neptune have methane in their atmosphere which absorbs red light, allowing the blue hues to be reflected. Neptune is a lot more of a blue colour than Uranus, but Uranus has more methane in its atmosphere. Its though that other constituents in Neptune enrich its blue colour.
No. There is no oxygen in Neptune's atmosphere
Neptune. It depends on what is being compared: core of planets OR atmosphere of planets.

It is a gassy planet like Jupiter, Uranus, and Neptune
Uranus and Neptune are both gas giants, but Neptune appears darker than Uranus because of its deeper blue coloration. This difference is primarily due to the presence of methane in Neptune's atmosphere, which absorbs red light, making the planet appear darker overall.
There is more methane gas in the highest levels of Neptune's atmosphere than there is on Uranus, this makes Neptune appear blue. Most of the gas in Neptune's atmosphere is hydrogen and helium. The atmosphere is stormier than that of Uranus because the inside of the planet is warmer, which stirs up the gas. Neptune also has ice particles in the atmosphere and ammonia deposits from the exposed molten ammonia core.
