Level Cowl 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 cuculla, monk's-hood-or-hood-of-habit. As a color modifier, cowl implies a monk's-hood-and-deeply-folded-hood quality, the visual register of Benedictine-and-Cistercian-monk's-cowl hand-monk's-hood-and-deeply-folded-hood Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey cowl-and-monk's-hood surfaces under Benedictine-and-Cistercian-monk's-cowl-and-Cluny-Abbey Cluny-and-Cîteaux-Abbey monastic-cloister-light. Sits at the modifier-and-textile end of the grid, parallel to cloak and frock 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.
