Disciplined Knight Teal

Latin disciplīna, teaching / training — past-participle of discipline. As a color modifier, disciplined implies a clear-and-controlled-and-careful quality where the hue carries the visual register of careful-edited-and-restrained design-decision. Sits at the crisp-and-orderly end of the grid, parallel to methodical and orderly in usage.

Old English cniht, young-man / knight. As a color modifier, knight implies a chivalric-and-armored quality, the visual register of English-Plantagenet-and-French-Capetian hand-forged plate-armor-and-shield-and-lance-and-pennant knightly-and-chivalric surfaces under English-Plantagenet-and-French-Capetian chivalric-armored-knight ceremonial-court light. Sits at the modifier-and-cultural end of the grid, parallel to squire and page in usage.

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
