Color of chemicals - Wikipedia

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths..

How Fireworks get their Colors Strontium Metals Salts …

The colors were actually produced by heating metal salts, such as calcium chloride or sodium nitrate. For example, if you put copper in fire, it will glow with a blue flame and a good strong blue flame is the best background to a great fireworks, enabled by copper oxychloride. Adding strontium to that blue mix gives a red flame and adding
