why do elements produce different flame colours when heated?

Because the atoms are of different sizes, and with different energies of their electron levels. In the flame, electrons get excited, and jump up a few levels. Then they fall back again, and give out particular frequencies of light. If the atoms are different, so is the light they emit.

when we supply heat energy to the substance by heating, the energy is used for the electronic excitation of the molecule. as it cant stay in the excited stage for a longer time, it returns to the ground state by emitting radiations in the visible region, thus elements produce colour on heating.
