During daylight the sky of Earth has the appearance of a deep blue surface, as the result of the air's scattering of sunlight. At night the sky has the appearance of a black surface or region scattered with stars. During the day the Sun can be seen in the sky, unless covered by clouds. In the night sky the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. On Earth, birds, insects, aircraft, and kites are often considered to fly in the sky. As a result of human activities, smog during the day and light radiance during the night are often seen above large cities. The light from the sky is a result of diffuse sky radiation which results in a light blue color being perceived by the human eye. On a sunny day the earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon. It can turn a multitude of colors such as purple (especially near sunset and sunrise) and black at night. Scattering effects also partially polarize light from the sky. So, I guess the sky is any color it appears to be, and I'm guessing it looks grey to you?

Two nights ago at sunset we had a gloriously clear sky here in Dallas. The sky overhead was almost black and it shaded downward toward the horizon where it was a glowing yellow almost white. Going up in order, the yellow shaded to a darker redder orange, then to a bit of almost violet then to a light blue that progressed through dark blue to the black up high.
When the sun is in the sky, the sky is a light blue because moisture in the air scatters the blue, so we see it all over while red and yellow travel straight through. If there is little or no moisture and no dust, the sky is a deeper blue - seen in mountain areas in winter and desert or plains areas after rain has washed dust out of the air and dry air has moved in.
If colors were music, pure deep blue would be a clear pure tone from a horn scaling up in frequency as it got lighter. Red would be fast pulsing raggety jazz sound of a red, with deep reds moving toward oboe. Yellow is a lighter sound, maybe a brassy high trumpet, perhaps muted.

the sky could have been violet if the sun were a bit hotter, it's because there is less violet light than blue that the sky looks blue. Violet light will be reflected the most. The sky can be red at sunset, black at night, grey when it's cloudy. Also the color of the sky is affected by your eyesight, the sun is actually more green than yellow, but our eyes are more sensitive to yellow light so that's how we see it. Snakes would see the sky as infrared possibly?

It's one of those things that can't be described. There's a special term for them. Well, it's just looks different. Say if you had a bunch of black and white stripes, some one else would see different stripes. It's like something tastes sweet and something bitter, there's no way to explain it. I'd say sky has a suddle oily creamy taste, really neutral, like oily water. Pink is creamy and sweet. Black it bitter. White is neutral though. But not oily like blue. Green tastes like veggies. Red is spicy. Oragne is sweet and citrusy. Unlike a yellow that's just plain citrusy. There are other colors too, but they are the same just not as intense. Like light yellow, is like a bit of lime juice in a glass of water. While yellow is pure juice.

If you are colorblind, what purpose would there be in telling you the colors, as they would mean nothing to you? You already know the day sky is blue and the night sky is black. Even a totally blind person would know that just because it is referred to so much.
Juwiegr...the person said colorblind, not blind. I'm sure she can see birds, the sun, the stars, clouds, etc.
(Personally, I think she's having us on a bit. Anybody who is truly colorblind would have given up asking such questions long before learning how to use a computer.)

I believe that the reason that it is blue, for most of the day, is because nitrogen (not exactly sure) reflects blue light the most, and the sky also turns red and purple during sunset and sunrise, however I cannot remember which elements cause this.

Hi. Nitrogen is a very light blue gas. Think of the feeling of having your hand in cool water and you'll get the idea.
