Low temperature because red giants are star with low temperatures, but very bright.
A star forms when a portion of a dense interstellar cloud of hydrogen and dust grains collapses from its own gravity. As the cloud condenses, its density and internal temperature increase until it is hot enough to trigger nuclear fusion in its core (if not, it becomes a brown dwarf). After hydrogen is exhausted in the core from nuclear burning, the core shrinks and heats up while the star's outer layers expand significantly and cool, and the star becomes a red giant.

Which color star has the lowest surface temperature?
Red
Which types of star has low temperature and high luminosity?

What causes different colors?
A star's color is caused by the type of gases its made up of and the temperature. The temperature changes depeding on the age of the star. Older stars turn red due to the amount of space it has to heat up.
What is the color of a cool temperature star?
Red is the coolest star and blue is the hottest.
When a star changes from blue to red what happens to the surface temperature?
The temperature is lowered.
What are the hottest and coolest stars?
the temperature of red star is minimum and maximum for blue stars . our sun is yellow colored therefore red stars are coolest than our sun . Take the example of Wolf 359 (a type of red dwarf star ) located in the constellation Leo . the temperature of photosphere of this star is about 2800 kelvin and the temperature of sun's photosphere is 5778 kelvin ( effected )
Color of star with temperature of 3000 Celsius?
red
