The primary color of the sun in the visible spectrum is white. While the sun appears yellow to us when seen from Earth, due to atmospheric scattering of light, it emits light across the entire visible spectrum, which includes all colors. When combined, these colors form white light. A clear view of the sun's light, such as during a solar eclipse or from space, can show its true color more accurately. Understanding this phenomenon helps in grasping concepts related to light, energy, and the effects of Earth's atmosphere on the perception of sunlight.
