Mineral elements provide the color in fireworks. Additional colors can be made by mixing elements:

bright greens barium barite
deep reds strontium celestite
blues copper chalcopyrite
yellows sodium halite (rock salt)
brilliant orange strontium + sodium celestite, halite

Gold sparks are produced by iron filings (magnetite, hematite) and small pieces of charcoal.

Bright flashes and loud bangs come from aluminum powder (bauxite).
