Color plays an important part in how we see the world. From the door of his eyes, humanity can see many different shades. Countless colors surround us from burnt orange leaves to crimson flowers, from snow-white to ink-black concrete, etc.

But when we look at the Earth from outer space, it will sparkle like a sphere with two tones of blue and green. This is because the Earth is 71% water and there are trees on the ground. Not only our planet, but every other planet in the Solar System has its own unique color.

When we think about color, we see it as merely a visual clue. However, in reality, color is not a tangible object as it is a message transmitted between the human brain and eyes.

According to Pantone, color perception is how our brains translate our ability to absorb light. So while we perceive an apple as “red” this is actually just a message our eyes tell our brain that the object – in this case an apple – is reflect a specific wavelength of light. Each object is recognized by our brains with a different color as a way of labeling the amount of light that the object reflects. On Earth, our photoreceptors can translate about a million colors around us on all sides.

The color of the planet will depend on the main material on its surface

According to Cool Cosmos, one of the factors that influences the color of each planet is the matter found on their surface. For example, Mercury’s topography is mainly composed of carbon-rich material, specifically graphite, so the planet can be seen through a telescope as gray. But this gray is completely different from the gray of the White Moon, because the gray of the Moon is the result of iron, not graphite.

According to scientists, Mercury’s graphite plates are not only found on the planet’s surface. They are also likely to lie beneath the planet’s crust, a clue to what the planet looked like in the past.

The planet’s atmosphere also contributes to its distinct color

Like the surface material, the atmosphere also affects the reflection and absorption of light. This also contributes to the color of the planet. The burnt orange and pale yellow attributes they see on Venus, for example, are actually dense layers of carbon dioxide and sulfuric acid in the planet’s atmosphere.

NASA reports that Uranus has a cool blue color because it has a certain amount of methane in its atmosphere. Interestingly, the methane on Uranus absorbs red light but reflects it back into space as blue.

Referring to red, we cannot help but mention Mars, the planet famous for its fiery red appearance. According to Space, Mars has more iron from its surface to its core, which many scientists believe is a result of its smaller size and weaker gravity compared to Earth. Under different circumstances, all that iron would make the planet gray. However, Mars has a rather thin atmosphere, but it also contains a certain amount of oxygen, and this causes iron to oxidize, which then turns the planet red.

Storms can also change the color of the planet

When we think about the colors of a planet, we often assume that their color is fixed and constant. However, because color is considered light that is reflected or absorbed, this means that violent storms on the planet can change the color of the planet as winds move through the atmosphere. In other words, the color of a planet will not be completely fixed, especially when the planet has some strange weather phenomena going on.

According to Universe Today, this is exactly what is happening on Jupiter. A gas giant in the Solar System and also a planet with a relatively high number of storms. Accordingly, this planet has many colors and is not fixed. Some parts of Jupiter are always affected by storms and fluctuations in color, changing from red to white depending on the temperature of the storm’s core, Business Insider reports.

The thickness of cloud cover and fog also affects the color of the planet

NASA reports that planets can have amazingly similar properties but still have different colors, for example Uranus and Neptune. These two planets have almost the same appearance in terms of matter, mass, atmosphere, and even size.

Accordingly, they must have the same color when observed from space. However, they have different shades with Neptune being blue and Uranus being blue. New research suggests the difference is because Uranus creates a thicker layer of haze that covers the entire planet and makes its blue appear duller, at least to the human eye.

In fact, our ability to perceive light is limited due to human biology, which makes us blind to many colors in the universe. According to NASA, our telescopes are designed to pick up small portions of infrared and ultraviolet wavelengths invisible to the human eye but visible to other Earth creatures such as birds and frogs. nurseries and butterflies. However, even this advanced technology does not capture the entire spectrum of light, which means that all planets can have completely different colors from what we just see.
