Sora: The secrets behind its color

We are always amazed how the sky turns blue during day time and red orange during sunsets. Why does the sky have these colors?

Is the sky really blue? Is it because of the ocean?

Before I start answering these questions I advised everyone to further their readings and study, the facts that I will share is based on the info I gathered.

The color of the sky have something to do with the wavelengths of colors present in a rainbow. Why does it appear blue? The sky is blue when you look at it but it actually consists of all the colors of the rainbow. Each color possessed varying wavelengths. Blue light waves travel in short, choppy waves. Like each of the other colours, blue light waves are scattered and reflected as they enter Earth's atmosphere and collide with gases and other particles. The color blue, having the shortest wavelength, collides with almost everything in its path and is scattered, that's why it appears that the sky is blue. The largest portion of gas present on the earth's atmosphere which is Nitrogen, is the gas that blue light mostly collides and reflects off of as it makes its way toward Earth. We will be seeing a different color of the sky if not for nitrogen and short wavelengths of the blue color.

Then what is the real color of the sky?

Although we often see it as blue, sky sometimes turn pale blue, white, and grayish which have something to do with pollution. The sky doesn't have true or single color.

  • Deep blue sky - clean sky. This often occurs when a cold front brings clean air from the north, or when clean air from the ocean moves onto land.

  • Medium blue sky - This colour means there is lots of water vapor in the sky. It can also suggest the presence of sulfur from coal-burning operations. Moreover, it may be caused by the chemical emissions of plants and trees.

  • Pale or milky white sky - This colour indicates considerable air pollution from coal-burning power plants or chemical power plants. This condition often occurs in the summer when the air is still. There are also natural causes, such as volcanic activity or ocean plankton.

  • Gray or dark gray - smoke from forest fires or agricultural burns can cause the sky to appear this colour.

  • Brown or brownish orange - Emissions from cars and trucks can cause a layer of this colour to form over the horizon. The main component of this kind of pollution is nitrogen dioxide.

Does the blue sky is caused by the ocean?

As I've stated, the blue color have short wavelengths that enables to collide with other gases and is the color visible to our eyes, so no, it is not caused by the ocean.

How about the red color during sunset?

According to the science magazine Scientific American, the sunset is reddish because "when the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only colour light that is not scattered away is the long wavelength light, the red."

There some rare instances that we see purple skies, the wavelength of purple is much shorter than blue but we didn't see it often because our eyes can't see every color of the spectrum, given that blue is a dominant color, we often see the sky as blue even tho purple is also scattered in the sky.

That's some of the secrets of sky colors, I once thought it have something to do with the ocean but guess it's about wavelengths.💙


Sora is a Japanese word for Sky

I am always in love with deep blue sky, and now that I've learned that blue sky indicates a clean sky, I came to love it more. Hope you learned something 😊

Thanks for stopping by♥️

I love the orange sky, it's beautiful. The blue sky isn't caused by the ocean. Does the blue sky cause the blue ocean instead? The water reflects the blue sky that's why we also see it as blue ocean hmm🤔

Hmm i wonder, but i guess not some oceans are green too. I think it's also about the absorption and scattering of the wavelengths of light😊
