This is the most beautiful scientific diagram I've ever seen.
Also a great example of why pink is a tint of red, but also a completely different color. Erbium? Neodymium? So beautiful.
FYI Neodymium glass (aka Alexandrite glass to collectors) appears different colors under different lights:
This image is from a great writeup of why that happens on the Jennii Neutron blog.
Oh and of course Uranium, Selenium, Manganese, and Cadmium all fluoresce under black light.
None of these are poisonous to drink from or meaningfully radioactive, btw, but they will leech heavy metals into things stored in them the way that leaded crystal will.
