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.
Red
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.
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.
Alioth is a white star nearing the end of it's main sequence. Hope this helps! (:
its a blue color
A main sequence star's temperature is most closely related to its color and brightness.

A main-sequence G2 star refers to a star that is in the main sequence phase of its life cycle and has a spectral type of G2. The G2 classification refers to the star's surface temperature and color, with G2 stars like our Sun being yellow-white in color. These stars are fusing hydrogen in their cores and are stable in their energy production.
Rigel B is also a blue-white star but, unlike Rigel A, it is a main sequence star.
No. Red giants are not on the main sequence.

A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
