What colors have white in them?
White can make a lot of other colours. For example, if you project white light through something clear e.g. glass, then you will get a little rainbow.

What do they put in cobalt glass to make it blue?
Cobalt is known for blue colouring: cobalt silicate and cobalt(II) aluminate (CoAl2O4, "cobalt blue") provide a distinctive deep blue color to glass, ceramics, inks, paints and other substances. Cobalt was added to the glass to protect the liquids it might contain from damaging light rays. (Image courtesy of Jurii, Creative Commons Attribution 1.0 license.) But like its sister transition metals, cobalt can assume a number of beautiful colours besides blue.
What are glow sticks made out of?
Glow sticks are generally made of a fairly tough but flexible translucent outer casing of plastic, and an inner capsule of thin glass. The pair of chemicals that are responsible for the chemiluminescence are held inside and are kept separated until the glow stick is deployed. One of the chemicals is inside the glass capsule, and the other is "around" it inside the plastic case. The idea is to get one of the chemicals needed to make the "glow" isolated inside the plastic case, and then allow the other chemical to be "around" the glass capsule and inside the plastic. That way when someone bends the plastic case or strikes it sharply on a hard surface, the glass capsule will break safely inside and release the chemical it held. The two chemicals then combine and the chemical reaction produces light.
