Well it was pink,but Lord Rayleigh decided a few years ago that blue sounded better.

The molecules of gases in our atmosphere scatter sunlight; the color scattered the most without being absorbed is blue - that's what we see. When the sun is down, although the same effect is true for starlight, it's so dim that we can't detect the blue. So, the atmosphere appears to be clear to our eye.
The effect is called "Rayleigh scattering."

The sky is black where we live.

The sky is blue because of the fact that the gas Earth's Atmosphere (mostly Hydrogen gas, Carbon Dioxide Gas, and Oxygen Gas) refracts "white" light similar to passing white light through a prism, which causes the atmosphere to appear "blue" to the human eye. The earth's magnetic fields also protect it from certain wave lengths of light, sending this wave lengths back into space. This refraction occurs at the molecular level.

The sky is not blue. It is the reflection from the sea.

Sunlight being refracted through our atmosphere and what is holds
Including Water Vapour
It acts like a Spectrum to lengthen the Wavelength to the Blue end
It is known as Rayleigh Scattering
After Lord Rayleigh, who first proposed itSource(s): Lord Rayleigh

the nature of sunlight and how it interacts with the gas molecules that make up our atmosphere.
It's only blue when it's clear or partly cloudy
If it's very cloudy it's gray
Sunrise or sunset, more yellow-orange
If it's nighttime it's black

you can google that question and you will get the correct answer why do you ask it here

Same as the last 90,000+ times this has been asked.

We see blue when the Sun is high in the sky because that's the upper energy level of sunlight that is refracted downward to where we are standing on the ground. The air is acting a bit like a prism and we are seeing the blue end of the spectrum when the sky is blue.
In sunset and sunrise, we often see the red sky because the lower energy end of the spectrum is refracted down to where we are standing to see the sky.
