excited state
Most fireworks add some chemical to make the color red, green, blue, etc.
What happens is that the energy from the blast vaporizes the chemical, the atoms of the chemical absorb energy and move the atom(s) from the ground state to the excited state. The excited state is not stable and it returns to the ground state (either in one step or several) but each step results in the release of energy in the form of a photon and all of the photons together produce a spectrum of that specific chemical.
