Sun

Sun light is actually more green than any other color, but if a brave human were to be in space and stare at it, it would look pure white.

The yellow, orange and red tones humans see from Earth are just the result of the sunlight being filtered by the atmosphere, which absorbs blueish wavelenghts and lets the reddish ones pass.

Mercury

He is so small he doesn't have much atmosphere, that's why what human eyes would see is just its gray rocky surface, and maybe some really slight glimpses of red due to high reflectance deposits that resulted from volcanic activity.

Venus

With a really thick atmosphere with huge sulfuric acid clouds, the surface of Venus would be a mistery if it weren't for the probes that landed there. When a human looks at it from space, he sees a very pale, almost white yellow shade. Venus is also the brightest object of earth's night sky.

Earth

When viewed from space, the human home planet has predominant beatiful shades of dark blue, cloudy areas look white and pastel blue and, if you're lucky, you can see brick-red continents and occasional dark green vegetation patches.

Moon

It looks beautifully grey up there in the sky. The darker spots are the lunar seas (or lunar maria), large plains of a different shade of ancient volcanic material.

Humans like to stare at their Moon with awe and romantic eyes. Following their dream of exploring the Universe, humans are actually planning to build there a Moon Village.

Mars

The rusty rocks of Mars and the dust suspended in the atmosphere make it look reddish brown when a human sees it from space. Some areas are tinted with darker browns because they have different reflectance properties (albedo). If you look carefully and you are lucky enough to visit Mars when there are no giant dust-storms, you'll also see many white shades in the caps because of huge ice deposits.

Jupiter

There is no surface to see in the big gaseous bodies of the Solar System. Rotation and powerful storms makes Jupiter look like dressed in parallel stripes of pale orange/brown and white shades. If a human were to look carefully, he would also find some tints of blue, which are just areas with fewer clouds that would allow him to look deeper into Jupiter's heart.

The Great Red Spot in the lower right area is a huge storm the size of Earth that is believed has been active for at least 350 years now. The lower left black spot is one of Jupiter's moons shadows passing by.

Saturn

Saturn also dresses in stripes like his neighbor, but Saturn would look of various shades of pale gold to a human in orbit, and much less contrasted because of lower density clouds. Depending on the season, the difference in temperature between the north and south hemisphere makes one look a little more pale blue than the other.

Saturn rings might look pale sandy and grey, but if a human were close enough, he would be also able to see some beautiful shades of light pink. In the image, the middle dark spot is the shadow of one of Saturn's many moons, Enceladus.

Uranus

To a human observer, Uranus shines in a pleasant and consistent shade of pale blue, with slight traces of greenish blue, a common light absorption characteristic of Methane.

Lately, electronic eyes have found some interesting fireworks that are happening under the Methane mist.

Neptune

Neptune looks pale blue much like his brother Uranus, but a human observer would be able to see some interesting differences, like a prominent spot that appears darker because of lower clouds and some horizontal stripes in greyer blues and occasional white spots, which are believed to be made of frozen Methane.

Pluto

Pluto shows his love for the Solar System with a huge glacier in the shape of a heart that is believed to actually beat over time, colored in a contrast of light and dark earthy browns.
