Complexes containing metals with d 0 electron configurations are typically colorless because

Complexes with d 0 electron configurations do not have any unpaired electrons in the d orbital, and therefore there are no d electrons that can be excited to a higher energy level by the absorption of visible light. This means that the complex does not absorb any visible light, and so it appears colorless.
