In case of star’s temperature, color is a measure because there are diversified wavelengths of colors which are emitted by stars. The temperature of every star is the basis on which the changes in the color of every star depend. There are areas in which there can be the finding of emissions of every star to be concentrated. It is in these areas that there can the observance of the connection/relation of the temperature of every star with the wavelength of light. It is in wavelengths that there can be the determination of every star’s emitted energy. Cool stars show tendencies of being measured by infrared wavelengths or even by red wavelengths.
