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)
Typical flame test colors are the same as coloring compounds for fireworks. Calcium gives a Red-Orange. Boron gives bright Green. Barium is Yellow-Green. Copper (II) as a halide gives Bluish-Green. Other Copper (II) salts give a Emerald Green. Molybdenum gives a Yellowish Green. Phosphorus gives a Pale Bluish Green. Lead, Tellutium and Antimony are Pale Green.
