Reposeful Gloam Teal

Latin repōnere, to put back — adjectival suffix -ful. As a color modifier, reposeful implies a clear-and-restful-and-still quality, the calm color of pre-modern monastic cloister-and-refectory meditative-and-silent interior architecture. Sits at the crisp-and-calm end of the grid, parallel to peaceful and placid in usage.

Old English glōm, twilight-or-dusk. As a color modifier, gloam implies a twilight-and-half-light-and-fading quality, the visual register of Scottish-Border-and-Hebridean-gloam hand-twilight-and-half-light-and-fading Scottish-Border-and-Hebridean-and-Orkney gloamed-and-twilight-and-fading surfaces under Scottish-Border-and-Hebridean-and-Orkney long-northern-twilight-and-blue-hour gloaming-and-twilight light. Sits at the modifier-and-mood end of the grid, parallel to dusk and shade 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.
