The white light given off from the sun will hit the atmosphere, and as the atmosphere nears the horizon it actually becomes thicker than when it is straight overhead. The thicker atmosphere changes the wavelength from blue, which is a shorter wavelength, to orange or red, a longer wavelength.
If the morning skies are of an orange-red glow, it signifies a high-pressure air mass with stable air trapping particles, like dust, which scatters the sun's blue light. This high pressure is moving towards the east, and a low-pressure system moves in from the west.
Red light has a longer wavelength than blue light and is not scattered as easily. The orange sky was caused by the contribution the aerosols were making to the way the light was being scattered.
A coming storm is one of the most common causes of a yellow sky, and a yellow-ish, orange hue might indicate a winter storm brewing on a relatively warm day. When you first notice a yellow-orange tone in the sky, it can create an eerie atmosphere or simply be a cause for fascination.
The most heavily polluted cities in the world also tend to have more orange and red sunsets, resulting from an abundance of human-made aerosols. Though the result can be spectacular to observe, it is also an indication of increased air pollution.
A yellow sky usually just means a thunderstorm storm is brewing. Storm clouds can scatter the normal blue light in the sky, which sometimes creates a creepy yellow or even greenish glow (especially late afternoon storms when the sun is lower on the horizon).

An orange or red Sun in the early morning or late evening is a sight to behold. The sky takes on these vivid hues due to a phenomenon called Rayleigh scattering.
TL;DR - the turbulent air and excessive moisture generated by the storm scatters short wavelenghts of light (blue/violet) away, leaving only warmer hues (orange/red).
Small smoke particles preferentially scatter blue light, leaving mostly orange and red light – this is why smoke turns the sky orange!
Orange Skies Day was a climatological event that occurred in the San Francisco Bay Area on September 9, 2020.
Dust from the Sahara Desert has fallen across Spain, turning the sky rusty orange too. Many people woke up to see the red-orange coloured sky and were left bewildered.
Why does the sky sometimes turn orange after a thunderstorm? Most thunderstorms occur in the late afternoon. By this time of day, the sun is beginning to set. The orange hue is caused by the same process that causes the vivid colors at sunsets.
WHAT WE FOUND. Panovich says it's a mere coincidence that the sky turns green before a tornado. He says because severe storms usually happen later in the day, the sun is at the exact right angle to create this color in the sky.
"Water/ice particles in storm clouds with substantial depth and water content will primarily scatter blue light," officials at the NWS office Hastings, Nebraska. "When the reddish light scattered by the atmosphere illuminates the blue water/ice droplets in the cloud, they will appear to glow green."
There are several atmospheric warning signs that precipitate a tornado's arrival: A dark, often greenish, sky. Wall clouds or an approaching cloud of debris. Large hail often in the absence of rain.
Apparently not. It can vary. The belief is held due to the fact that a green cast to the sky indicates heavy hail/rain and the yellow is often due to dust in the air.
A pink, or technically red, sky at night meant good weather for the next day. This is because as the sun is setting, its light is traveling through the lower parts of the atmosphere. The red color comes from particulates in the air, such as dust and moisture.
A red color in the sky is the result of sunlight reflecting off clouds. If the sky is red in the morning, the eastern horizon must be clear, and the clouds foretelling a coming storm are in the west, indicating the potential for bad weather.
Code Orange on the Air Quality index represents unhealthy air quality for sensitive groups. Older adults, younger children and those with respiratory conditions such as asthma should limit prolonged or heavy exertion outdoors.
In winter and at higher latitudes, sunlight passes more tangentially through the earth�s atmosphere and travels a greater distance. As a result, some of the blue light is scattered away and more of the orange light reaches our eyes. This explains the color but not the crispness of my orange-blue sky.
A red sky appears when dust and small particles are trapped in the atmosphere by high pressure. This scatters blue light leaving only red light to give the sky its notable appearance.
The other colours pass through the Earth's atmosphere to reach us, but because of the great abundance of blue light wavelengths, our eyes see the sky as blue. Technically, the short wavelengths that scatter across the sky correspond to the colours blue and violet, making the real colour of the sky a bluish purple.
In the living world beneath our red-ravenous atmosphere, blue is the rarest color: There is no naturally occurring true blue pigment in nature.
