Some stars are closer to the Earth than others. Why is it that some stars appear to have color while other simply appear to be white? The color receptors in our eyes are not sensitive enough to detect color in fainter stars and as a result only the brightest stars in the sky appear to have color. It seems that the stars with 'cooler' temperatures have energy that is radiated in the red tones of the electromagnetic color spectrum, while those with 'hotter' temperatures had energy that is radiated in the blue and white tones of the electromagnetic color spectrum.
