Fire is the heat and light released during a chemical reaction that oxidizes the fuel.
Different elements of the fuel will emit different wavelength photons that can identify what is burning.
For example, green indicates copper, red is strontium, yellow for sodium, etc.

Fire is a plasma of carbon ions from flammable material--whether paper, wax, oil, coal--that have lost electrons owing to the heat. As the electrons return to the carbon ions to form carbon atom soot, they give off yellow light, which we call fire.
