Its temperature. Red stars are stars with a cooler temperature, typically because the outer layers are much farther from the center of the star, where the fusion actually occurs. Most "main sequence stars" like the Sun are destined to enter a red giant phase as they exhaust their supply of hydrogen, and they begin to expand as reactions occur around an inert helium core.

Betelgeuse is a red giant star and comparatively cool.
Betelgeuse is a red giant.
A non red giant is a giant, whereas a supergiant is well a supergiant and is a lot bigger.
The star called Betelgeuse is a red giant. It is about 700 times the size of the sun, and its temperature is lower than that of the sun's, at around 6,000 degrees Fahrenheit.
A red color, in a star, is associated with a low surface temperature.

No. Betelgeuse is a red super-giant star, the red star at the left shoulder of Orion the Hunter.
Yes, Betelgeuse is a red supergiant star located in the constellation Orion, while Aldebaran is a red giant star located in the constellation Taurus. Both stars are considered giant stars, with Betelgeuse being classified as a supergiant due to its larger size and more advanced evolutionary stage compared to Aldebaran.
