A red giant star.
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.

They are classified by the amount of Light they give off, and their temperature.
At a higher temperature, the star will shine more brightly for each square meter of surface. The total luminosity per square meter is approximately proportional to the fourth power of its absolute temperature. This refers to the energy output, considering all types of electromagnetic waves, not just visible light.
