United colors of plutonium

Plutonium, like a lot of the other transition metals, has a number of oxidation states and all of them are colorful. The valence ranges from +3 to +7, with +4 being the most common state.

This image was provided through Los Alamos or Lawrence Livermore National Laboratories; Wikipedia claims it's from LLNL but LANL uses it on a page at their site. The four colors on the right are the +4 valence forming different complexes with different anions.

I edited the image and concatenated the colors together for a palette. It looks like some sort of bad hotel color scheme.

P.S. There is some discussion of the first separation of plutonium here:
