The Sun's true color, seen from space, is white. It only looks yellow on Earth because the atmosphere scatters its shorter blue and violet wavelengths away via Rayleigh scattering.. The peak wavelength in a spectrum also generally determines an object's apparent colour. So, for example, cooler stars appear red and hotter stars appear blue, with orange, yellow and white stars in between. For the Sun, the spectrum actually peaks at a wavelength that we would normally describe as green. However, across the narrow range of the visible spectrum the amount of light emitted at.
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 reason we often imagine the Sun as yellow or orange has to do with the air around us rather than with the Sun itself.
