Distant objects appear blue due to atmospheric scattering, particularly Rayleigh scattering. When light travels through the atmosphere, the shorter blue wavelengths are scattered more easily than longer red wavelengths. This causes a greater proportion of blue light to be scattered in all directions, making the sky appear blue. The same effect causes distant dark colored hills to appear blue because the atmosphere between the observer and the hills scatters the blue light, making it the dominant color that reaches the observer's eyes.
