Etymology

Drained
adjective

Old English drēahnian, to filter — past-participle of drain. As a color modifier, drained implies a deep-and-emptied-and-pallid quality where the hue's vital warmth has been removed. Sits at the deep-and-cool end of the grid, parallel to deathly with desaturation overtone.

Coronet
noun

Old French coronete, little crown — a small ornamental crown worn by lower-rank European nobility (dukes, earls, viscounts, barons) and Crown Princes of Britain. The coronet of an English duke is set with deep-blue sapphire. Coronet color refers to an English duke's coronet with its sapphire alternation: a saturated, slightly cool deep blue-violet with the glassy finish of polished Ceylon sapphire on gilt metal.
