Elliptical Galaxies.
The elliptical galaxy Messier 87 in the Virgo Cluster is known for containing mostly older stars with a reddish color. These stars are typically low in mass and have evolved over billions of years, giving the galaxy its distinct red hue.
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 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 have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.

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.

Young stars are blue because they are also hotter than older stars, which have cooled down to make white, yellows, then oranges, then red.
That sounds like the description of an elliptical galaxy.
The oldest stars are now mostly either white dwarfs or neutron stars. A few of the largest may be black holes.
The color of a dying star can vary depending on its size and age. Smaller dying stars tend to appear white or blue, while larger dying stars can appear red or even orange. The color is determined by the star's temperature and the chemical elements present in its outer layers.
