That sounds like the description of an elliptical galaxy.
A Spiral Galaxy
The galaxy is older than our Solar System.
By analysing the oldest stars found.The older the star, the older the Galaxy.
Generally, an Elliptical galaxy is the oldest type of galaxy.
Actually, it doesn't matter what kind of galaxy it is, because it depends on what kind of stars are in it. If a galaxy has a lot of red giants, it will appear redder than a galaxy with mostly blue-white stars. Older galaxies might be redder than younger galaxies due to the fact that older stars appear redder.
