As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
its a blue color
Our sun is a yellow main sequence star of spectral type G2 V
Sheliak, the star in the constellation Lyra, is classified as a blue-white main-sequence star. It appears bluish-white in color when observed.
A main sequence star's temperature is most closely related to its color and brightness.
White is the main color with black accents typically.
Red
Denebola is a class A star on the Main Sequence of the H-R diagram. Its burns with the white color typical of these large, hot stars.
The color of the star Megrez is bluish-white. It is one of the main stars in the constellation Ursa Major and is part of the Big Dipper asterism.
blue
Rigel B is also a blue-white star but, unlike Rigel A, it is a main sequence star.
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:
The absolute magnitude of a main sequence star with a temperature of 25,000K would depend on its luminosity, which is not provided in the question. However, at this temperature range, the star would appear blue-white in color, as it falls within the blue-white region of the stellar temperature-color relationship.
