- No, you often hear that, but—assuming you mean typical pollution in the lower atmosphere—it's a myth. It's actually the opposite: Large particles in the lower atmosphere tend to mute and muddy the colors because they absorb more light and scatter all the wavelengths more or less equally, so you don't get that dramatic filtering effect.

- Why is The Sky Blue
Most people think the answer is yes -- that smoggy cities like Los Angeles and Beijing, with hazy skies most of the time, at least get to have extra-brilliant sunsets to cough at as a result of that haziness. As it turns out, those people are mostly wrong.

Jul 18, 2018 · What causes a red sky at sunrise and sunset? The Sun is low on the horizon at sunrise and sunset. At these times of the day, sunlight has had to travel through more of the atmosphere to reach us. When light hits the atmosphere it is scattered, particularly when dust, smoke and other particles are in the air.
Even without air pollution, we would still experience red skies — at least to an extent. But as you’ve seen, excess pollution in the air can make sunrises and sunsets have a brighter red glow. It can even make the sky appear red at night or during the day. As the atmosphere continues to get more polluted, will the sky continue to turn red?
However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer...
Aug 23, 2012 · In places where natural light dominates the night sky, clouds typically make those skies darker, just as they do during daylight hours. But the researchers found that the opposite is true in urban areas: Clouds actually magnify the sky glow effect by reflecting more artificial light back down to Earth.
A display of reds, oranges and pinks spreading across the evening sky can be a spectacular sight. But what makes this happen?
