Why do fireworks make different colors?
Quick Answer
Different metal salts produce different colors when heated. The heat excites electrons, and each element emits its own characteristic light.
The Full Story
Fireworks rely on emission spectra, the specific wavelengths of light given off by excited atoms. Strontium compounds are often used for red, barium for green, sodium for yellow, and copper compounds for blue. When the firework burns, the heat energizes the atoms, and as the electrons return to lower energy levels, they release light. This is the same basic principle used in flame tests and some types of spectroscopy.
