Nebulae are associated with the end of a star's life cycle, as they are shells matter that blown off a star, usually in a series of events, when a star is in its death throws.
The color of emission nebulae is a result of the predominate gas or gasses in that nebulae. Different gasses glow in different colors. Blue, as the color of the star, indicates how hot the star is.
