Two things.
First, the magnitude of a star; its brightness
Then, the magnitude is viewed through two different filters.
They are either U(ltraviolet) and B(lue) or B and V(isual), and belong to a photometric system called the UBV system.
From this, optical astronomers extrapolate the effective temperature of a star from its colour.

How you can determine the star of a star planet?
You can determine star of a star planet by its color also you can determine its temperature by its color by:Joshua R. Dapitillo thanks=)
Does the color of a star determine its temperature?
YES!
Which property of a star can be determine by color?
temperature
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.
One way in which scientists can determine the surface temperature of a star is by its A. brightness. B. composition. C. color. D. mass.?
its color does determine the temperature of star.
If a star in the sky appears red What can you determine about the temperature of the star?
It would have a comparatively "low" temperature of 2,300 to 3,700 Kelvin.
What factors determine a stars brightness as seen from earth?
Distance from Earth, size of star, and temperature of star.
What factors determine a stars brightness seen from earth?
Distance from Earth, size of star, and temperature of star.
One way in which scientists can determine the surface temperature of a star is by its?
There are several things scientists can do to determine the surface temperature of a star. Formulas utilizing Wein's law and the Stefanâ??Boltzmann law can calculate stellar temperatures. However, for a rough estimate, scientists can also use the color of a star in order to determine surface temperature.
If you wanted to determine the temperature of a star what measurement would you take?
emission spectrum
What are three physical factors that determine a star's brightness?
Age of the star, size, and temperature. The answer is in another post that I saw.
If you wanted determine the temperature of a star what measurements would you make?
Emission Spectrum
