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.

Which galaxy is bigger a elliptical or irregular?
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
Can galaxies divided into types base on size?
are spiral galaxies are generally older than elliptical
What galaxy is smaller than a Spiral and Elliptical Galaxy?
By virtue of their name, dwarf galaxies are smaller. Most galaxies are dwarf galaxies.
What is a major difference between elliptical galaxies and spiral galaxies?
Eliptical galaxies have older stars than spirals and elipticals are oval-shaped.
Are there bigger galaxies than the Andromeda?
Yes. Some giant elliptical galaxies contain tens of trillions of stars.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
Are nebulas in elliptical galaxies?
Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
Why are galaxies are a disk and not like a spherical object?
Galaxies are generally disk shapped, rather than spherical because of centrifugal force: Just like throwing a pizza crust in the air, it expands in the direction of its rotation. However, older galaxies (possibly the products of collisions of two or more galaxies) can result in blob-shapped galaxies that are more spherical.
What is a galaxy that is shaped like an oval?
elliptical galaxies
Galaxies that have a bright center that contains very little dust and gas?
Stars come in a variety of types. Blue stars, which are very hot, tend to have shorter lifetimes than red stars, which are cooler. Regions of galaxies where stars are currently forming are therefore bluer than regions where there has been no recent star formation. Spiral galaxies seem to have a lot of gas and dust, while elliptical galaxies have very little gas or dust.
Galaxies are classified by their shape what are they called?
There are three types of galaxies, all of which are the same, with the exception of their shapes. There are the Elliptical galaxies (football-shaped) the Spiral galaxies (like the Milky way; vortex-shaped) and Irregular galaxies (all shapes other than spiral and football shaped).
