Blue stars are very hot stars and so usually have high luminosity.
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
If a star has a large luminosity and a low surface temperature, it must have a large surface area to compensate for the low temperature and still emit a high amount of energy. This would make the star a red supergiant, a type of star that is both luminous and cool at the same time.
I was enthralled by the luminosity of the deep water jellyfish.
A red giant star.
A hypergiant star appears red to the human eye due to its low surface temperature and high luminosity. However, some hypergiant stars can exhibit other colors such as orange or yellow depending on their age and chemical composition.

it is a very large star of high luminosity and low surface temperature.....=)))))

No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
