If a galaxy shows any significant colour band, then it is due to the type of stars present in that galaxy. A blue or white galaxy would have to have a predominant amount of OB stars to project that colour band.
Spiral galaxies do not have significantly greater amounts of OB stars, so it is only a "visual" appearance, not a factual one.
The main reason that spiral arms appear blue is that the arms are sites of star formation and are brighter than the surrounding disk.
The stars tend to be young, hot OB stars which are blue (blue-white) in colour.

What colors are spiral galaxies?
Blue, blue-white, white, yellow, orange, and red. In the visible spectrum. They also emit in non-visible wavelengths. Note that I don't mean it could be any of those colors, I mean it's probably ALL of those colors.
How do you use the hard blue and white spiral hair rods?
To use the white and blue spiral hard rods first section your hair off with a comb. Roll each section of hair with a spiral rod and secure with a hair pin.
Which type of galaxy mostly consists of a collection of older red stars that are located in the center with blue and white stars located in the outer regions?
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.
Compare the colors of spiral galaxy with the colors of elliptical galaxy?
Spiral galaxies tend to have blue colors due to the presence of young, hot stars that emit blue light. Elliptical galaxies, on the other hand, are typically redder in color because they contain older stars that emit more red light. This color contrast is a result of the different star formation histories and compositions of the two types of galaxies.
How do the characteristics of elliptical galaxies differ from those of spiral galaxies?
Elliptical galaxies are generally round or oval in shape, with older stars and little to no gas and dust. They have less organized structure and lack spiral arms. Spiral galaxies, on the other hand, have a flat, disk-like shape with spiral arms, younger stars, and more gas and dust for ongoing star formation.
What do spiral galaxies have a nucleus of?
A spiral galaxy nucleus contains a mass of stars in a "bulge" and is thought that many contain supermassive black holes at the very core of the nucleus.-In galaxies with tightly wound spiral arms the bulge generally contains old, red stars with low metal content (called population II stars); whereas galaxies with more loose arms generally have younger, blue stars (called population I stars). Some bulges have similarities to the elliptical galaxies and others are similar to disk galaxies.-Evidence of supermassive black holes have been discovered in many galaxies and theorized to exist in many more galaxies (at least the larger ones). Our own Milky Way Galaxy contains a supermassive black hole at its core.
What population stars are found in a sprial galaxy?
Spiral galaxies contain a variety of stars, ranging from young, hot, and blue stars to older, cooler, red stars. These stars are grouped in spiral arms that extend from the central bulge of the galaxy. The different populations of stars in a spiral galaxy contribute to its overall appearance and dynamics.
What types of stars do elliptical galaxies usually have?
Elliptical galaxies typically contain older, low-mass stars that are redder in color. These stars have lower levels of ongoing star formation compared to spiral galaxies. Elliptical galaxies also tend to have a larger population of low-luminosity stars, such as red dwarfs.
What are the colors of the columbine flower?
mainly blue with some white
Why there is a galaxy?
A galaxy is a cluster of stars, nebulae, dark matter, and other astronomical objects. Most galaxies are tens of thousands of light years in diameter, and contain billions of stars. Galaxies come in three primary shapes; spiral galaxies are thin disks, with spiral arms surrounding a central hub; elliptical galaxies are uniform, oval-shaped agglomerations; and irregular galaxies have little or no definite structure. A spiral galaxy centers around a hub, which is roughly spherical and bulges outward from the disk. The hub is the gravitational center of the galaxy, and usually contains a supermassive black hole. Surrounding the hub are spiral arms, which are bunched-up waves of stars and gas orbiting the center. The spiral arms usually have more gas and dust, and they contain most of the newly formed stars, which make them appear blue in color imagery. A spiral galaxy may have a horizontal bar passing through its hub; our own galaxy, the Milky Way, is believed to contain a bar.
How many different colors of stargate chevrons are there and which galaxies do they correspond to?
In our galaxy, they are grey with orange encoders, in the pegasus galaxy, they light up blue with blue encoders, and on the Destiny, they are white with white encoders.
What rivers help the Nile?
Mainly the Blue Nile and the White Nile.
