Hi. It's not. The light gets scattered and blue, being a shorter wavelength, gets scattered first. The rest, mostly red, is all that is left for the sunrise and sunset.

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.
Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

The atmosphere filters the light so what you see appears blue. At sunset the sky is reddish/ different colors because the light is coming from a different angle, it has to go through more of the atmosphere and that makes the color of the light appear different.

the sky is blue because the earth is covered with 75% of water.

Sky is blue because. Earth is two thirds water and it reflects that.

Wrong..wrong...Your all wrong. The public educational system has failed you. Please stop posting on yahoo answers you need to be getting help rather then giving it.

because blue has more frequency than any other colours so therefore it scatters more and you see blue more.. but when its sunrise or sunset the blue isnt as much a frequency .people als say that its reflected by the ocean thats a myth.

the little water droplets in the air reflect all blue light and absorb the other colors. so blue is all we see
