Which is hotter - a red star or a blue star? Why?

I know it's the blue star, but I don't know why...

    The radiation emitted by a star is to a good approximation thermal radiation. This then implies that the spectrum will be the Planck spectrum. The higher the temperature, the shorter the wavelength at which the emitted power will peak.
