So, a very slight excess of green light doesn't look green to the human eye - it looks white. The Sun would have to emit only green light for our eyes to perceive it as green. This means the actual colour of the Sun is white.
So, why does it generally look yellow? Answering the simple question of the sun's actual color reveals it's not yellow but green-peaked, a counterintuitive fact that led directly to Max Planck's quantum revolution. Learn what color the Sun is and why it appears different colors from Space, the Earth, and in photographs. Color, though, is how our brain interprets the full mix of light wavelengths entering our eyes.
The sun's peak intensity is at a green wavelength. But green is just one of many colors of light the sun emits. Sunlight spans the whole light spectrum.
The color of the sun reveals a range of information about our star including the stages of its life and how it interacts with the atmosphere of Earth. The sun is white-kind of. It depends on your interpretation of color, the way colors work, the way our eyes see and, just as importantly, the air we see through.
We'll go into why the blackbody effect means the Sun emits more green visible light than any other color, and why evolution and color perception mean it's ok to see it as yellow, anyway. Some say that the Sun is a green-yellow color, but our human eyes see it as white, or yellow-to-red during sunset. What color is it really? What Color Is The Sun? The sun's color is dependent on the sun's surface temperature, Earth's atmosphere, and the human eye The sun's light peaks in visible light around 500-nanometers, which translates to blue-green Earth's atmosphere causes the sun to appear yellow to our eyes When we look at the sun, either with protective equipment or with solar observatories, it appears yellow.
That's why the sun looks white to us." The sun reportedly has a little bit of yellow and white, but its real color is green. "When you calculate the sun's wavelength or visible light, it emits energy around 500 nm, which is close to blue-green on the visible light spectrum," according to Action News 5.
