    "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."

Etymology

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.
