Answer:
When visible light falls on a transition metal compound or ion, the unpaired electrons present in the lower energe d-orbital get promoted to high energy d-orbitals, called d-d transition, due to the absorption of visible light. ... Therefore, transmitted light shows some colour complementary to the absorbed colour.
