what is the color of the sky?

Answer 1

"The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue."

Answer 2

The short answer is that the sky has no color at all. In daylight however, the sky appears to be blue.
The 'sky' consists of a thin layer of colorless gases, which we call the atmosphere. When light from the sun interacts with the gases in the atmosphere, most of it travels straight through and reaches the ground. However, some of the light gets absorbed by the gas molecules in the air, and then immediately gets scattered in a random direction. The process is called 'Rayleigh scattering'.

Higher energy wavelengths of light are more prone to scattering then lower energy wavelengths. The higher energy wavelengths are bluish in colour, and the lower energy wavelengths appear reddish. So the bluish colors of light get scattered all over the sky, while the reddish colours go straigh through without being scattered.
The sky appears blue because blue light is being scattered in every direction by the molecules in every part of the atmosphere, while every other colour of light is passing straight through to the ground. So no matter what part of the sky you look at on a clear day, you see blue.
Unless you're looking directly at the Sun, which is a bad idea!

To answer more precisely, the color of the sky can only be best described as 'blue'. It varies daily and is affected by air density, humidity, and the presence of pollutants and various other substances in the atmosphere, such as dust, volcanic ashes and sulphur dioxides to name a few.

Answer 3

The sky is actually transparent. The reason you see colors in the sky is due to a refraction of sunlight from the particles in the atmosphere.

Answer 4

air is a mixture of oxygen, nitrogen, helium, noble gases and co2, so2,so3, etc. . . . . .these are all colourless gasses . . . . .so basically the sky is colourless. . . . however it appears blue during the day because the parcticles in the air ( very small cannot be seen with the naked eye ) refract or deflect the rays of light in different ways . . . .not blue light scatters more that all other colour(raleigh scattering) and hence gets deflected the most and then thus the sky appears blue but in all originality its colourless

Answer 5

Transparent

Whether the sky appears blue or red or gray has to do with refraction, reflection and absorption of light by the atmosphere, but the atmosphere itself has no color.

Answer 6

Earth's sky is usually pale blue, but other planets have different skies. It all depends upon the composition of the atmospheres of said planets.

Answer 7

Blue in the day time and black at night. And various other colors depending on how much cloud cover or smog or dust or smoke is in the air.

Answer 8

On this planet, it's blue due to the atmosphere being composed primarily of nitrogen which scatters light in that wavelength range.

What planet are you from? ☺

Answer 9

Doesnt have a color. I think we are looking at the reflections off particles in space.

Answer 10

black/grey/blue/red depending on the time of day and the weather.
