The other, less apparent property of most stars is their color. A few brighter stars look red, orange, or yellow, but most still look whitish or bluish. The physical property that most determines a star's color is its surface temperature. Typical stars have surface temperatures that are nearly uniform and that change very little over time. For those of you whose eyes just glazed over, a less technical explanation is that black bodies emit radiation that peaks at a characteristic wavelength, and which falls off in strength for wavelengths away from that peak.
Hotter objects emit radiation at shorter wavelengths.
The Sun has a surface temperature of about 5800 degrees Kelvin, and its peak emission wavelength is about 500 nm, which we have evolved to consider as right in the middle of the range of visible light. Typical star temperatures range from about 2000 degrees Kelvin to as much as 28,000 degrees Kelvin. Because the luminosity of a star is approximately proportional to its temperature to the fourth power, doubling the temperature of a star would increase its luminonsity by a factor of 16. A red star the size of our Sun would be too dim to be seen at any great distance. Blue stars, on the other hand, are visible for hundreds or thousands of light-years.
