Flame tests are useful in lab situations when it is necessary to identify a compound that is an unknown. This happens frequently when labels fall off of containers. Many fireworks get their color because salts burn brightly. Copper salts give fireworks a green color
Burning Salts - Sciencetheatre
We get to see this effect by burning the metal salts in ethanol, and can see as each salt gives out a different color. This effect is something that you may have already known, but never thought about. The majority of paints get their colors simply by adding a dye
Note: Due to the vivid and persistent colored flame produced by the sodium chloride, the flame color of sodium should be demonstrated last. When flame colors become less vivid and take on a yellowish tinge, it is time to dry them in an oven overnight.

Color of chemicals - formulasearchengine
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 .
Calcium Chloride - an overview | ScienceDirect Topics
As previously indied, calcium salts appear to have a superior activity compared with most other metal salts, but they commonly suffer from a low solubility in water. Calcium formate acts in a manner similar to calcium chloride, but high dosages are required and its solubility is considerably less (approximately 17 g/100 g compared with 75 g/100 g at 20°C).
What Colors are Produced by Burning different Chemicals …
Calcium salts burn orange. Salts are made up of a metal and a nonmetal. In each case, it is the metal that provides the color when the salt is burned. That is why both copper chloride and copper sulfate burn blue. Other metallic salts produce some outstanding
