Blue stars are the hottest whilst black dwarfs are the coldest. (However, no black dwarfs exist yet - see related question) The stellar classification [See link] in order of temperature. Our Sun is classed as yellow.
Stars can range in temperature, from the relatively cool red dwarfs to superhot blue stars. So what is the hottest star in the Universe? First, letâs talk a bit about temperature. The color of a star is a function of its temperature. If a star looks red, that means its surface temperature is approximately 2,500 Kelvin. Just for comparison, our Sun, which actually looks white from space, measures about 6,000 Kelvin. The hotter the star, the further up the spectrum you go. The hottest stars are the blue stars.
