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.

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 are the colors of the columbine flower?
mainly blue with some white
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 is the soccer team La Galaxy's colour?
mainly blue and white
What rivers help the Nile?
Mainly the Blue Nile and the White Nile.
What color is your microwave?
my microwave is mainly white and grey with blue and orange
