   Dust and Pollution. The quality of the air that sunlight has to pass through also has an effect on the color of sunrises and sunsets. Dust particles and pollutants tend to tone down the colors in the sky as well as impede light from reaching the observer on the ground. Because of this, the sky takes on dull hues of red and yellow when the air ...

   The sun rises in the east, so the light would give oncoming storm clouds a reddish hue — a red sky in the morning. The sun sets in the west. So if the sunset is red, that may mean that it’s illuminating the departing clouds, indicating that the bad weather is moving away.

   Jul 18, 2018 · 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. This scattering affects the blue part of the light spectrum the most.

   Why do we see Red Sky at sunset?

   • At the day’s end, though, the light has to travel through much more of the atmosphere, and those short, blue light waves have a tough time getting past all the molecules. They mostly get scattered away before they ever reach us. The result is that red sky we see at sunset, since longer red wavelengths are still able to penetrate the atmosphere.

   What does it mean if a sunset is red?

   • So if the sunset is red, that may mean that it’s illuminating the departing clouds, indicating that the bad weather is moving away. Sunrises and sunsets are probably the best-known causes of red skies. But thanks to a recent phenomenon, the night sky above urban areas sometimes glows red, too. You might already be familiar with “skyglow.”

   Why does the sky look blue at sunset?

   • At sunset, the sky at the horizon looks red because the light there is scattered least. The shorter, blue wavelengths are scattered more, so the sky appears bluer the further from the Sun you look.

   Why are some sunrises and sunsets redder than others?

   • You may have noticed that some sunrises and sunsets are redder than others. This tends to happen when there are more particles in the atmosphere. Smoke and other larger particles are particularly good at scattering red light. Unfortunately, air pollution from human-made aerosols also scatters red light very effectively.

   Why does a rising and setting sun have a red & yellow color?

   • Due to Rayleigh scattering, most of the light of shorter wavelengths – the blue, violet, and green – are scattered away multiple times, leaving only lights of longer wavelength – the red, orange, and yellow – to pass straight through to the observer. This is why a rising and setting Sun tends to take on spectacular hues of red, orange, and yellow.

   Why do sunrises & sunsets change color?

   • This is why a rising and setting Sun tends to take on spectacular hues of red, orange, and yellow. Dust and pollution can reduce the vibrancy of sunrise and sunsets. The quality of the air that sunlight has to pass through also has an effect on the color of sunrises and sunsets.
