Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames). The color of the flame is dependent on the metal ion; the anion of the salt has very little direct influence. The anions however influence the flame temperature, both

Flame tests using metal salts | Resource | RSC Eduion

When a metal salt solution is sprayed onto the flame the electrons in the metal are excited and jump from one electron shell level to the next highest shell level. They are said to be excited . They cannot remain there so as they return to the original shell, known as the grounded state the energy gained is lost in the form of light known as emission .
