Why are glass lining color options blue and white?

Usually the choice of which color to use comes down to concerns about cleaning and what particles could be left behind. If people are concerned with dark-colored particles being left on the surface, they will usually choose a white glass so they can see the particles either. If the particles are a lighter color, then you would choose a blue glass. Also, if you are going to be observing the reaction (using a vessel light) during operation, white glass tends to be a bit better in terms of being able to see what is going on inside.
