Transition metal ion colors

Are there certain transition elements that we should know the ionization color in an aqueous solution for ie. Nickel is green? Saw this come up in a question and not sure how low yield it is (I'm trying to be thorough)

There is no way to know an exact color without experimental determination. The important thing is to understand the concept. Understanding that transition metals often have multiple oxidation states, magnetic properties, fill their d orbitals and give colors are important concepts. Make sure you understand how to write electron configuration.

Hope this helps.
