Its probably totally unrelated...
but blue stars are much hotter than red ones, and blue light is of higher frequency (shorter wavelength) than red. Black-body radiators emit higher frequency radiation the hotter they are, so that red hot molten, metal, for example, is cooler than blue-hot metal. This certainly has nothing to do with with our perceptions of color and hue with objects near room temperature, or with the subjective or artistic idea that that red is the color of warmth, while blue is cool and refreshing.
