A possible explanation for the different colors of the Spiral, Elliptical, and Irregular galaxies comes from the types of stars found in those galaxy regions.

<h3>What is a spiral galaxy?</h3>

The spiral galaxy has twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars. For example, the Milky Way is a spiral galaxy with a rotating disc and spiral 'arms.'

The color of a spiral galaxy is much redder than the colors of irregular galaxies.

<h3>What is an elliptical galaxy?</h3>

An elliptical galaxy is a galaxy that has a generally elliptical shape, no apparent internal structure or spiral arms, with little dust and gas, and apparently a reduced population of stars. The main color is red.

<h3>What is an Irregular galaxy?</h3>

Irregular galaxies lack shapes. They are small galaxies filled with a lot of hot gas and dust with blue colors. There is a large population of stars here.

Thus, spiral galaxies are the most common, followed by elliptical galaxies (though much older and invisible), but irregular galaxies have bulging stellar populations due to the presence of too much hot gas and dust.
