When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

Answer:
how does this happen? Flame colouration: It is the colour imparted to the flame when a mineral is fused in the flame. ... When the excited electron comes back to the lower energy level, it gives out the extra energy in the form of visible light an thus gives characteristic colours to the flame.
