Every metal that gives blue begins with a "c": copper, cobalt, chromium, cadmium; every metal/substance that gives green begins with a "b": barium, boron...?

It was a mere joke, but funny, isn't it?
Barium is a multi-colour metal. It gives, green, yellow, blue and white depending on salt and composition.
