Various colors of plutonium in solution. Caption for image: "The color of plutonium oxidation states. Each oxidation state, ranging from Pu(III) to Pu(VII), has a characteristic color in solution. Plutonium will often change oxidation states in solution, making its interaction with the natural environment inordinately complex."
