During the day, the sun appears as a bright yellow or white orb in the sky. This color perception is primarily due to the scattering of sunlight by the Earth's atmosphere, which filters and disperses the sunlight's wavelengths. When the sun is high in the sky, especially around noon, its light is more direct and appears whiter. However, during sunrise and sunset, the sun may take on more orange and red hues due to the longer distance its rays travel through the atmosphere, allowing more scattering of shorter wavelengths. Overall, its daytime color is a key feature of our celestial experience.
