Level Mute Teal

Latin libella, small-balance / level-tool — sharing root with libra (balance). As a color modifier, level implies a clear-and-horizontal-true quality where the hue carries the visual register of gravity-perpendicular-and-perfectly-horizontal surface. Sits at the crisp-and-balanced end of the grid, parallel to plumb and flat in usage.

Latin mutus, silent-or-dumb. As a color modifier, mute implies a hushed-and-tongue-stilled-and-quieted quality, the visual register of silent-film-and-monastic-mute tongue-stilled-and-cloister-quieted silent-film-and-monastic-and-cloister tongue-stilled-and-still-and-quiet surfaces under silent-film-and-monastic vigil-and-cloister hush-and-quiet vow-of-silence light. Sits at the modifier-and-mood end of the grid, parallel to hush and still 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.
