Transition metals usually from coloured complexes and d-d transitions (t_(2g)hArre_(g)) are responsible for colour as the energy difference between t_(2g) and e_(g) lies in visible region. But all the coloured ions are not dut to d-d transition but charge transfer bands also play important roles. Charge transfer bands may be of two types. (i) ligand to metal (CTLM) " "(ii) metal to ligand (CTML). Charge transfer transition always produces intense colour as compared to d-d transition. MnO_(4)^(-) is dark purple coloured though Mn is in (+VII) oxidation state with 3d^(@) configuration
