Symmetrical Moor Kingfisher

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 mōr, waste / marshland. As a color modifier, moor implies a heather-covered-upland quality, the visual register of Yorkshire-and-Scottish-Moors heather-and-bracken-covered peat-bog-and-grouse-shooting upland surfaces under late-summer purple-heather Yorkshire-and-Highland atmospheric light. Sits at the modifier-and-place end of the grid, parallel to bog and wold in usage.

The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
