The Sun’s surface temperature (5, degrees C) produces a range of visible light (red to blue) in which yellow is the most plentiful, but not much more than other colors it produces. If the Sun were cooler, say 2, degrees C, it would look red, like the stars Antares and Betelgeuse.
As the light waves bounce in lots of different directions, we say they have been scattered. Now we can proceed to your question. But that is only because its short-wavelength colors green, blue, violet are scattered out by the Earth's atmosphere, much like small waves are dispersed by big rocks along the shore.
Some think that the Sun's output in visible light peaks in the yellow. However, the Sun's visible output peaks in the green: Image from Art Neuendorffer So why are the solar images sometimes green, or blue, or red, or orange?
View current images of the Sun Actually, all forms of light and energy are part of the same phenomena: Our eyes can detect only a small amount of this energy, that portion we call "visible light.Grateful Dead - Scarlet Begonias (Studio Version)
Scientific instruments can sometimes detect light that our eyes cannot. When people want to look at those, say, X-ray or ultraviolet images, they need to color them something that our eyes can detect.The sky was yellow and the sun was blue Strangers stopped strangers just to shake their hand Everybody’s playing in the Heart of Gold Band Be the first to review “Scarlet Begonias: The sky was yellow and the sun was blue ” Cancel reply.

So the scientists pick some bright color, a color that would never be confused with viewing the Sun in white light. That way, we know from seeing a picture of a neon green or bright red Sun that the image was actually taken in some non-seeable version of light such as extreme ultraviolet or X-rays.
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.
Large particles of pollution or dust scatter light in a way that changes much less for different colors. The result is that a dusty or polluted sky is usually more grayish white than blue.
Similarly, cloud droplets typically 10 millionths to millionths of a meter are much larger than visible light waves, so they scatter light without much color variation. This is why light scattered by clouds takes on the same color as the incoming light.
For example, clouds will appear white or gray at midday and orange or red at sunrise or sunset. This is why sunsets or sunrises are so much prettier when some clouds are available to show us the colors.
Why is the Sky Blue? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through.
Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules.Grateful Dead - Scarlet Begonias (June 28, 1974)
The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you.
Since you see the blue light from everywhere overhead, the sky looks blue.Why is the Sun Yellow? I had a good feeling. The remaining colors together appear yellow.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions.
Less blue light reaches your eyes.
