Detailed explanation-1: -The surface temperature of a star determines the color of light it emits. Blue stars are hotter than yellow stars, which are hotter than red stars.
Detailed explanation-2: -The sun has a surface temperature of 5, 500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3, 500 K for a bright red star and 2, 500 K for a dark red star. The hottest stars are blue, with their surface temperatures falling anywhere between 10, 000 K and 50, 000 K.
Detailed explanation-3: -Color temperature is a scale relating the color of light radiated by an object to its temperature. As color temperature rises, so the light emitted shifts towards bluer hues. In practice, the actual temperature is not the same as the color temperature, which is the reason correction factors are used.
