The True Color of the Sun .If you view sunlight through a prism, you can see the entire range of wavelengths of light. Another example of the visible portion of the solar spectrum is seen in the rainbow. Sunlight isn't a single color of light, but a combination of the emission spectra of all the elements in the star. All of the wavelengths combine to form white light, which is the net color of the sun. The sun emits different amounts of various wavelengths. If you measure them, the peak output in the visible range is actually in the green portion of the spectrum (not yellow). However, visible light isn't the only radiation emitted by the sun. There's also blackbody radiation. The average of the solar spectrum is a color, which indicates the temperature of the sun and other stars. Our sun averages about 5,800 Kelvin, which appears nearly white. Out of the brightest stars in the sky, Rigel appears blue and has a temperature exceeding 100,000K, while Betelguese has a cooler temperature of 35,00K and appears red. www.thoughtco.com/why-is-the-sun-yellow-603797
