From German Kobalt, formerly also Kobald, ‑olt, ‑old, ‑elt, ‑el, apparently the same word as Kobold (“goblin”), from Middle High German, which became also a Harz Mountains silver miners’ term for rock laced with arsenic and sulfur, so called because it degraded the ore and made the miners ill. Doublet of kobold.

   • 2025 February 21, Leah Dolan, “How the Superman ‘S’ became fashion’s favorite logo”, in CNN‎:

     And although we’ve certainly seen a variety of blue shades — from periwinkle to cobalt and even Dean Cain’s indigo-washed costume from the 1990’s TV show “Lois & Clark” — Superman’s uniform is still instantly recognizable across generations. In fact, there is only one film — Zack Snyder’s 2013 “Man of Steel” — in which Superman does not wear his iconic red belted trunks.
