The hotter an object is the shorter the wavelength of light it emits as a shorter wavelength means more concentrated energy. Blue light has a shorter wavelength than most other colors, so the hottest stars are blue.
It's kind of the other way around: they're blue because they're hotter, not hotter because they're blue.
Blue light is more energetic than red light, so it requires a higher temperature to produce.
If you'd like to know more details of exactly how this works, look up the term "black body radiation" or "cavity radiation".
