Red stars are the coolest of the stars.
However, for completeness:
Red stars have the lowest surface temperatures.
A star's color in the Hertzsprung-Russell diagram is determined by its surface temperature. Hotter stars appear blue or white, while cooler stars appear red.
The surface temperature of Denebola is approximately 8,500 degrees Celsius (15,400 degrees Fahrenheit). Denebola is a white main sequence star in the constellation Leo, and its high surface temperature gives it a bluish-white color.
The temperature affects the color of a star.
Intermediate mass stars are typically yellow in color. This color is a result of their surface temperature and the stage of their evolution.

Red stars have the lowest surface temperature compared to other colors of stars. Their cooler temperatures give them a reddish appearance.
The star color that represents the hottest temperature is blue. Blue stars have surface temperatures exceeding 10,000 degrees Celsius (about 18,000 degrees Fahrenheit) and are among the most massive and luminous stars in the universe. In contrast, cooler stars appear red or orange, with lower surface temperatures. The color of a star is an important indicator of its temperature and stage in the stellar life cycle.
The Color of stars depends upon their surface temperature.

The color is basically an indication of its surface temperature.
The stars in the constellation Hercules vary in color from blue to yellow to red, depending on their temperature. The surface temperature of stars in Hercules typically ranges from 3,000 to 30,000 degrees Celsius.
