Symmetrical Icicle Teal

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Old English īsgicel, ice-and-icicle.

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.
