Many people still believe that the sun is yellow, but the sun is actually white, though it often appears yellow, orange, or red from Earth due to atmospheric effects.
Why it looks different
In Space: Without an atmosphere to scatter light, the Sun appears as a brilliant white sphere. On Earth: Atmospheric particles scatter shorter blue and violet wavelengths (Rayleigh scattering), leaving behind the longer yellow and red wavelengths that we see. At Sunset: Light travels through more atmosphere, scattering even more blue and green, which turns the Sun deep orange or red.
💡 Key Fact: Sunlight contains all the colors of the rainbow. When these colors are mixed together, our eyes perceive them as pure white light.
