What makes up the star or element.
Elliptical galaxies tend to be reddish in color because they are made up of older stars that emit more red light. These galaxies have used up most of their gas and dust, resulting in a lack of ongoing star formation. This makes their overall color appear reddish compared to younger, bluer galaxies.
