 * Good job on adding citation to the article
 * I like the history section
 * the principle section added can be improved. When talking about excitation of electron, it is nice to mention electrons are getting promoted from HOMO to LUMO and back.
 * When talking about lights emitted in two visible region of the light spectrum you can elaborate more. From my knowledge transition metal compounds are coloured because of transition of d-orbitals. Some organic compounds are coloured if they have conjugation; Electrons are coming down form п* orbital to п orbital which emits light in visible region.
 * Figure is nice but missing the orbitals, so in the case of transition metal indicated the d orbitals (t2g, eg)
