Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
Elliptical Galaxies.
The Milky Way galaxy contains mostly older stars with a red color, particularly in the central bulge and halo regions. These stars are typically red giants and red dwarfs, which have aged and evolved from their initial blue color to appear red as they reach the end of their life cycles.
Elliptical Galaxies.
A globular cluster. These dense spherical collections of stars are typically found around the outskirts of galaxies and are among the oldest known star groupings in the universe. Their red color is due to the abundance of older, cooler stars within the cluster.
Elliptical galaxies mostly consist of a collection of older red stars in the center, with blue and white stars located in the outer regions. This is because elliptical galaxies have a smooth, featureless appearance and are dominated by older stellar populations in their central regions.

Elliptical Galaxies.
The central bulge of our Milky Way galaxy contains older stars, mostly red and yellow in color. These stars are typically found in globular clusters and form a dense, spherical region at the core of the galaxy.

That sounds like the description of an elliptical galaxy.
The galaxy is older than our Solar System.
Elliptical galaxies mostly consist of a collection of older red stars in the center, with blue and white stars located in the outer regions. This is because elliptical galaxies have a smooth, featureless appearance and are dominated by older stellar populations in their central regions.
Generally, an Elliptical galaxy is the oldest type of galaxy.
