The Sun's color is white, with a CIE color-space index near (0.3, 0.3), when viewed from space or when the Sun is high in the sky. When measuring all the photons emitted, the Sun is actually emitting more photons in the green portion of the spectrum than any other. When the Sun is low in the sky, atmospheric scattering renders the Sun yellow, red, orange, or magenta. Despite its typical whiteness, most people mentally picture the Sun as yellow; the reasons for this are the subject of debate. The Sun is a G2V star, with G2 indicating its surface temperature of approximately 5,778 K (5,505 ° C, 9,941 ° F), and V that it, like most stars, is a main-sequence star. The average luminance of the Sun is about 1.88 giga candela per square metre, but as viewed through Earth's atmosphere, this is lowered to about 1.44 Gcd / m. However, the luminance is not constant across the disk of the Sun (limb darkening).\n\nTemperature of the surface of the sun in kelvin? Let's think fast. Stream of consciousness:

The relevant information to answer the above question is: The Sun is a G2V star, with G2 indicating its surface temperature of approximately 5,778 K (5,505 ° C, 9,941 ° F), and V that it, like most stars, is a main-sequence star. So the final answer is approximately 5,778 K.
