Blue when it is young and red just before it dies.
Kochab is an orange giant star, so it appears orange in color.
Red giants are so named because they appear predominantly red in color due to their relatively cooler surface temperatures compared to other stars. The color of a star can indicate its temperature and age.
A red giant star appears red in color due to its cooler surface temperature compared to other stars. The red color is produced by the cooler temperatures causing the star to emit more red light than other colors.
The star Scheat is typically observed as having a reddish or orange color. This coloration is due to its classification as a red giant star, indicating its cooler temperature compared to other types of stars.
A supergiant star can have different colors depending on its temperature. A hotter supergiant star will appear blue or white, while a cooler supergiant star will appear red or orange.

Cygnus ob2 no.12, a hyper star is & also the biggest.
It's a giant red star.
A star is considered "dead" when nuclear fusion stops in its core. The name of the a star before this happens depends on its size. If its a star the size of our own, Sol, then it will be called a red giant. If it is considerably lager then it will be called either a giant, bright giant, super giant or hyper giant. This again depends on its size.
Kochab is an orange giant star, so it appears orange in color.
Polaris is a red giant star.
Red giants are so named because they appear predominantly red in color due to their relatively cooler surface temperatures compared to other stars. The color of a star can indicate its temperature and age.
Gamma Draconis, also known as Eltanin, is an orange giant star. It has a spectral type of K5III, indicating its orange hue and giant status.
A red color, in a star, is associated with a low surface temperature.
first its called the main sequence star like the sun then it becomes a red giant then it becomes a red super giant and if it is huge a hyper-giant like VY Canis Majoris (largest star known) then it explodes and it becomes a planetary nebula then it becomes a white dwarf
It is an orange giant with a spectral class of K3....
