The sunlight get through the atmosphere and gets bounced at the depth of the water bodies and this reflection is in such a way that the clouds come in their way,... there are several tones of blue color,...

I am a chinese girl. My chinese teacher in primary school teaching us "blue sky white cloud" when we learn chinese. She said when we see blue sky and white cloud then the weather is very good so we can go for pinic. My art teacher always said to us "Dont color the sky white and the cloud bule" lol. So i think God made the sky blue.:D

The sky is blue because air scatters short-wavelength light in preference to longer wavelengths. 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.
