The outer atmosphere of Jupiter is mostly hydrogen and helium, with some water droplets, ice crystals, and ammonia crystals. When these elements form clouds, they create shades of white, orange, brown, and red, the colors of Jupiter.
The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red. Even the gas giants are different, Neptune and Uranus an opaque blue, while Jupiter and Saturn are mostly beige with brilliant red-brown belts.
Viewed from Earth, Saturn has an overall hazy yellow-brown appearance. The surface that is seen through telescopes and in spacecraft images is actually a complex of cloud layers decorated by many small-scale features, such as red, brown, and white spots, bands, eddies, and vortices, that vary over a fairly short time.
Saturn is also a giant gas planet with an outer atmosphere that is mostly hydrogen and helium. Its atmosphere has traces of ammonia, phosphine, water vapor, and hydrocarbons giving it a yellowish-brown color.
The vivid colors you see in thick bands across Jupiter may be plumes of sulfur and phosphorus-containing gases rising from the planet's warmer interior. Jupiter's fast rotation – spinning once every 10 hours – creates strong jet streams, separating its clouds into dark belts and bright zones across long stretches.

Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.
Pluto's visual apparent magnitude averages 15.1, brightening to 13.65 at perihelion. In other words, the planet has a range of colors, including pale sections of off-white and light blue, to streaks of yellow and subtle orange, to large patches of deep red.
Viewed through a telescope, Venus presents a brilliant yellow-white, essentially featureless face to the observer. Its obscured appearance results from the surface of the planet being hidden from sight by a continuous and permanent cover of clouds. Features in the clouds are difficult to see in visible light.
The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune's methane atmosphere. Clouds elevated above most of the methane absorption appear white, while the very highest clouds tend to be yellow-red as seen in the bright feature at the top of the right-hand image.
Mars, known as the Red Planet, is a mostly dry and dusty place. A variety of colors can be seen on the surface, including the predominant rusty red the planet is known for. This rusty red color is iron oxide, just like the rust that forms here on Earth when iron oxidizes – often in the presence of water.
Mars is a rust-orange color. (We know, it's called the Red Planet—what can we say? It's orange.) Jupiter is a light tan color and Saturn is a yellow-ish tan color.
The outermost ring of the planet Uranus turns out to have a bright blue color, according to a report in the April 7 issue of the journal Science. That makes it only the second blue ring to be found in the solar system.
See those reddish areas around Jupiter's equator and poles? They look that way in the “rainbow” photo because of atmospheric particles—a kind of hydrocarbon smog—absorbing ultraviolet light. The blueness in between is caused by the ultraviolet light being reflected off Jupiter.
It is estimated that the temperature of the cloud tops are about -280 degrees F. Overall, Jupiter's average temperature is -238 degrees F. Since Jupiter is only tilted slightly more then 3 degrees on its axis, seasonal fluctuations are minimal.
Venus is entirely covered with a thick carbon dioxide atmosphere and sulphuric acid clouds which give it a light yellowish appearance.
Saturn is yellowish in colour and has many rings and satellites.
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. Water covers most of Earth.
Our galaxy is aptly named the Milky Way — it looks white, the color of fresh spring snow in the early morning, scientists now reveal.
What color is the Moon? It depends on the night. Outside of the Earth's atmosphere, the dark Moon, which shines by reflected sunlight, appears a magnificently brown-tinged gray. Viewed from inside the Earth's atmosphere, though, the moon can appear quite different.
Mercury is of green color and reflects green rays.
When you see Mars in the night sky, it definitely has a reddish tint to it. People have been noticing that for a long time: even the ancient Egyptians called Mars 'The Red One.
So today we would like to present you a story about the greenest planet in the solar system — Uranus.
