Properties of Calcium Chloride – Peters Chemical Company
Calcium chloride is used as a raw material in the production of high purity calcium carbonate, which in turn, is used to manufacture phosphors (material used to coat the inside of fluorescent lamps).These phosphors are low in metal ions.
WELCOME TO CHEMISTRY!
Just as a fingerprint is unique to each person, the color of light emitted by an element heated in a flame is also unique to each element. In this experiment, the characteristic color of light emitted by calcium, copper, lithium, potassium, sodium, and strontium ions will be observed.

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 .
