The Planet’s Colors
The planet’s actual colors are simple. Mercury is gray; Venus is a pale yellow; Jupiter is yellow with white bands; Mars is a reddish brown; Saturn is a pale gold; and Uranus and Neptune are both a pale blue. This means that some planets can get the same color, with the same substance or not. It is interesting to know these facts, but knowing how they get these stunning colors is a whole different story.
Uranus and Neptune get their color from the methane gas. Methane is a colorless, odorless gas. Because those two planets both have the same color, the gas must be in both of their areas. Mercury gets the plain color gray from the rocks and dust that are on its surfaces. Jupiter and Saturn both get their color from the ammonia clouds, a colorless gas with a bad smell, that hang around their atmospheres, and those clouds cause planets to have the colors white or pale yellow. This shows that there are many gases in space, for instance methane and ammonia.
This is Neptune
Venus’s clouds are not ammonia, but they also give the planet it’s yellowish color, meaning that there are many other different clouds that give the same colors. For example, if another planet had a bunch of clouds surrounding it, and the planet was yellow, that would suggest that the clouds might have the same materials that the ammonia clouds do. According to Curios Astro, “The assignment of colors is somewhat subjective.” That tells us that some people might see the planet's colors differently. Even though that is true, we can still get the general idea of what the planet’s colors are.
