Symmetrical Helen 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.

Greek Ἑλένη, Helen-of-Troy. As a color modifier, helen implies a Helen-of-Troy-and-fairest-face quality, the visual register of Helen-of-Troy-and-Tyndareus-Sparta hand-Helen-of-Troy-and-fairest-face Helen-of-Troy-and-Tyndareus-Sparta-and-Iliad-Homeric helen-and-Helen-of-Troy-and-fairest-face surfaces under Helen-of-Troy-and-Tyndareus-Sparta-and-Iliad-Homeric Mycenaean-and-Trojan Bronze-Age-Aegean-light. Sits at the modifier-and-myth end of the grid, parallel to eros and hera 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.
