What does the sun produce more yellow light than any other color? What is its surface temperature?

The sun appears to produce more yellow light than other colors because its surface temperature corresponds to the peak of its blackbody radiation curve, which falls in the yellow-green region of the visible spectrum. The sun's surface temperature is approximately 5,500 degrees Celsius (9,932 degrees Fahrenheit) or about 5,800 Kelvin. This temperature is often referred to as the effective temperature of the sun.
