SUMMARY
The shade of blue in the sky varies with latitude and altitude due to the scattering of sunlight by atmospheric molecules. At noon on a clear day, the sky appears differently at the equator compared to the North or South Pole, primarily influenced by the sun's position in the sky. While the equator experiences the sun directly overhead, the poles see it at a much lower angle, affecting the perceived color. Additionally, the sky's color does not translate to a blue hue from space due to the vast distances and atmospheric scattering effects, which do not create a blue "wall" on the horizon.
