The colors we see in the sky at sunrise and sunset are some of the most beautiful and captivating sights in nature. But what causes those stunning red, orange, yellow, pink and purple hues? The colors are determined primarily by the scattering of sunlight off molecules and particles in Earth's atmosphere. Here we'll explore the science behind sunrise and sunset colors.
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. A setting sun is a beautiful orange color that's unrivaled in nature, but how can a bright yellow ball of fire that's impossible to look at safely during the day suddenly become a soft, orangey. During a sunset, however, light scattering works differently.
The sun's light has a lot further to travel. Their presence during sunset serves as a reminder of their importance in the Earth's delicate balance and the interconnectedness of the natural world. In the grand theater of the sky, clouds are the ultimate collaborators, transforming the mundane act of sunset into a breathtaking spectacle of color, light, and texture.
During the day, when the sun is high in the sky, shorter wavelengths of light, such as blue and violet, scatter more efficiently. This is why the sky appears predominantly blue. However, as the sun approaches the horizon during sunrise and sunset, its light has to travel through a thicker layer of the atmosphere.
The high-altitude clouds serve to reflect strongly reddened sunlight still striking the stratosphere after sunset, down to the surface. Some of the most varied colors at sunset can be found in the opposite or eastern sky after the Sun has set during twilight. As the sun sets, the light travels through more atmosphere, allowing the shorter wavelengths to scatter away, highlighting the warmer colors.
This captivating phenomenon often leaves you pondering the deeper sunset color meanings found in art and nature.

Andrew Zaleski. The sun appears orange or red at sunrise and sunset because of Rayleigh scattering. As sunlight moves through the atmosphere, shorter blue wavelengths scatter away.
This allows longer red and orange wavelengths to shine through. Clouds also reflect this light, enhancing the warm colors we see during these moments. Heat and atmospheric conditions also play roles in these vibrant colors.
