I really love the color blue.  it is such a soothing color!
Distant objects look more blue because of an effect called atmospheric perspective.
I didn't know that.  so the sky i guess appears more blue than it is b/c of that.
The sky only appears blue. It's really just an optical illusion called Rayleigh scattering.
oh interesting.  I wonder what color it really is?
It is just a combination of a scattering of light particles.
wow thats neat!  I am glad it appears as blue though b/c I love that color.
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
is called aerial perspective or atmospheric perspective. The more distant the mountains are, the less contrast the eye sees between the mountains and the sky.
The bluish color is caused by an optical effect called Rayleigh scattering. The sunlit sky is blue because air scatters short-wavelength light more than longer wavelengths. Since blue light is at the short wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than long wavelength red light. The result is that the human eye perceives blue when looking toward parts
