The color of the stars is very important as it is directly related to its surface temperature. The extremely hotter stars appear to be bluish in color and the less hotter stars appears to be reddish or yellowish in color. The temperature of hot bluish stars ranges from 10,000 K to 50,000 K. The sun's surface temperature is inversely proportional to the wavelength of lights. The blue stars are comprised of lights that peaks at shorter wavelengths and have extremely high temperatures. On the other hand, the yellow stars are comprised of lights that peaks at longer wavelengths and have a comparatively lower temperature.
Thus, the stars that are bluish in color are of high intensities compared to the yellow stars.
