What's the real color of the sky?
463892
There is no such as the "real" color of the sky. The reason the sky is blue during the day is because the color of the light that the sun shines is white. And as you may know, white is the presence of all color and black is the absence of color.\n\nSo, the white light that the sun emits contains every possible color of light.  Now, each color of light has a different wave length depending on where it is on the color spectrum.  Red light has the longest wave length and blue/violet light have the shortest.  And since blue light has the shortest wave length, you see more of it's waves.\n\n\nsorry... that's the best i can explain it

When sunlight travels through the atmosphere, blue light scatters more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange. \nI could go into explaining it, but I'm too tired at the moment. Check out here:

sky blue is my choice.

The sky is blue due to the way that light is bent, it's called Rayleigh Scattering.  Sunlight is white and white light consists of all colors but when it hits our atmosphere the light is broken up into it's component colors by the particles in the atmosphere.  The shortest wavelengths don't make it through the particles but the blue light does - hence the sky appears blue when in fact it has no color ro it (it is after all, nothing but air and water).\n\nAs others have said - grass is green because of chlorophyll - the chemical in all plants and it just happens to be green.

I was interested by this so I did a bit of research.\n\nApparently:\n\n"When the air is clear the sunset will appear yellow, because the light from the sun has passed a long distance through air and some of the blue light has been scattered away.  If the air is polluted with small particles, natural or otherwise, the sunset will be more red."\n\nSo, I suppose the answer would be a more 'orange' sunset, and possibly less vibrant.  Wikipedia says: the "Color of a sunset may be enhanced by atmospheric phenomena such as clouds, smoke and smog."

light green and sky blue...

The sky is blue to us beause of Rayleigh scattering.  From outer space, you don't have that atmosphere effect, so it's black.

AHHHH !!!!A question other than why is the sky blue.  The color of the sky is colorless, clear.  Look at the shots of earth from space (on the night side) you can see earth perfectly, no color enhancement.  Look up at the stars on a clear night, you can see them without any bluish color.\n\nThe sky is only various colors when the sun is shining thru it.

WHY IS THE SUNSET RED?   \n\nAs the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected  and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to  orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer  wavelengths are left in the direct beam that reaches your eyes.   \n\nThe sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.

The atmospheric conditions are affecting the refraction of light & hence it doesn't appear to be blue today.

da sky is blue da clouds r white

not really true, the sky is blue because of the light waves produced by the sun, although it is believed that the sky is blue because it is reflected off the ocean, it is not necessarily true. The sky is blue because the water vapor molecules inside the air is breaking up the combined light "white light" into different frequencies of the light red being the strongest and penetrate through the water vapor, blue and violet being the weakest gets reflected back into the sky, if you noticed when you're on a plane at first at low altitudes the sky is blue, as you get higher the sky turns violet cool isnt it ^^...yes im a 10th grader but you don't need to know that

Why is the sky blue ?  Why is the sun yellow ? That is a very logical question guy please, lemme see um cause maybe JUST MAYBE if we do it standing up like you guys, how do I put this umm not a pretty picture right ?  so duh !

The sky is blue because of scattering of the sunlight by the atmosphere. According to Raleigh's law," The amt of scattering is inversely proportional to the 4th power of wavelength".Hence the shorter wavelengths r scattered much more than the longer ones. According to Raleigh's Scattering Law,blue light is scattered to a greater extent than red light. This scattered radiations causes the sky to appear BLUE.

I have no idea what you are asking. The question "why is the sky blue?" has been asked over 500 times here. Use the search engine to find some great material. \n\nYou want data that proves the sky is blue? The variable might be the wavelength of the light (or frequency). If you want to learn about the equations, look up Rayleigh-Tyndall scattering. The scattering intensity is roughly proportional to L^(-4), where L is the wavelength.
