The temperature of a star determines it color. Ones that are more reddish stars are colder than ones that are more yellow and yellow stars are colder than blue and white ones. lovefromabove25 Â· 9 years ago.
Stars have a range of colors which represent their surface temperatures due to Wien's law (which states that the peak emission of light from an object goes as the inverse of temperature). The color of a star is determined by that part of the visible spectrum where the peak amount of radiation is emitted.Blue stars are extremely hot, red stars are relatively cool. Temperature here is a relative thing; cool means temperatures near 2,000 to 3,000K, about 15 times hotter than your oven.lue stars have temperatures near 20,000K. The Sun is an intermediate yellow star with a surface temperature of 6,000K. The color of a star is determined by measuring its color index.
