History & Origin

Cobalt is a word-name from the metallic element and its deep-blue pigment. The word traces to German 'Kobold' ('goblin'), a nod to miners who found the ore hard to work. As a given name it is a bold modern color-and-element pick, which we note honestly (said 'KOH-bawlt').

In the U.S. it appears only rarely as a name. Vivid, modern, and singular.

Did you know? Cobalt is both a metal and a famous shade of blue — its name comes from German 'Kobold', a goblin miners blamed for troublesome ore (said 'KOH-bawlt').
