The early stages of a red giant are characterized by the star burning hydrogen into helium in a shell around the core, which causes the outer layers to expand and cool, giving the star a red color. This stage comes after a star has exhausted the hydrogen fuel in its core and the core contracts and heats up until it can begin fusion in a shell.
