That means that the different types of metals used in the stars each have a characteristic color. Here are some of the metals and specific compounds that are typically used in fireworks to produce different colors: Red: strontium (strontium carbonate, SrCO3), for intense reds and lithium (lithium carbonate, Li2CO3, or lithium chloride, LiCl) for medium reds. Orange: calcium (calcium chloride, CaCl2)
Barium is used to create green colors; it also helps stabilize and oxidize firework mixtures. Stronium brings red color to fireworks, and helps stabilize and oxidize firework mixtures. Calcium helps deepen the colors of the other elements, and brings a silver color and a little bit of red to the fireworks.
