When a beam of sunlight strikes a molecule in the atmosphere, what’s called “scattering” occurs, sending some of the light’s wavelengths off in different directions. But at sunset, the light takes a much longer path through the atmosphere to your eye than it did at noon, when the sun was right overhead.

Sunset colors are created by a phenomenon called Rayleigh scattering. It’s the same phenomenon that makes the sky appear blue during the day. Sunlight contains all the colors of the rainbow. Nitrogen and oxygen molecules in our atmosphere act as little mirrors for blue and violet light, in particular.

Sunset is distinct from twilight, which is divided into three stages, the first being civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon; the second phase is nautical twilight, between 6 and 12 degrees below the horizon; and the …

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.

It is orange-red because the sunlight reaching the dense smoke has already been reddened by less dense smoke. | Jim Hatcher in San Diego, California, captured this very red sun on September 7, 2020. The red color was caused by smoke in the air due to wildfires in the West this week.

The Answer: Red sky at night, The origin of the red sky proverb can be traced back to the Bible where in the book of Matthew, Jesus says to a group of fishermen, “When it is evening, you say, ‘It will be fair weather, for the sky is red’ and in the morning, ‘It will be stormy today, for the sky is red and threatening.”

The phenomenon of scattering is also why the sky turns red, orange, and pink at sunset. The science is the same, with short-wavelength blue and violet light scattered by molecules in the atmosphere while longer-wavelength red, orange, and pink light passing through and hitting the clouds.

The “red sky” trick gets around this by using the sun. Red wavelengths pass through air more easily than blue ones. When the sun is setting in the west, its light passes through hundreds of miles of atmosphere — becoming extremely red in the process — before hitting the clouds above you.

Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. The result is that the sunlight takes on an orange or red cast, which we can see reflected from clouds or other objects as a colorful sunset (or sunrise).

Earth’s atmosphere is primarily made of nitrogen and oxygen, which are the perfect size to refract blue light—which is why the sky is generally dominated by blue light. Only the red and yellow light are able to pass through these smoke particles, leading to these orange tinted skies.

If the sky near the Sun is blue at dawn, there is not so much scattering as usual and more UV would come to you from that part of the sky. Summary: An orange sky should have less UV coming from it than from a blue sky, but remember that looking directly at the Sun itself is dangerous.

“Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. This is why sunsets are often yellow, orange, and red.”

Orange represents confidence, joy and enthusiasm. ORANGE SPIRITUALLY EFFECTS – Creativity, emotional balance, sexuality, harmony, passion, freedom, intuition, and expression of emotions.

Orange. Orange is obtained by mixing red (flesh) and yellow (trials). The result is a color of fire which represents the Fire of God, deliverance and passionate praise.
