These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction. Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames).
Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.
Barium chromate – used in delay compositions, e.g. in fireworks rockets; Lead chromate – used in delay compositions; Potassium dichromate – used infrequently as an oxidizer; can be used as a surface treatment for passivation of magnesium particles, also as a catalyst and in some matches; potassium perchlorate often added; Oxides and ...

Copper gives fireworks a blue color. Lithium or strontium powder turns them red. Mortar shells — the quintessential aerial fireworks you see in the big displays — require careful assembly ...
Strontium aluminate is frequently used in glow in the dark toys, as it is chemically and biologically inert. [69] Strontium salts are added to fireworks in order to create red colors. Strontium carbonate and other strontium salts are added to fireworks to give a deep red colour. [70] This same effect identifies strontium cations in the flame test.

Aluminium metal is used to produce silver and white flames and sparks. It is a common component of sparklers. Ba: Barium: Barium salts are used to create green colors in fireworks, and it can also help stabilize other volatile elements. C: Carbon: Carbon is one of the main components of black powder, which is used as a propellent in fireworks.
