Even Kilt Teal

Old English efen, flat, equal — used as a color modifier since the medieval period for hues that read as uniformly distributed across a surface. Even gray, even tan: the implication is moderate saturation combined with optical uniformity. Sits at the crisp-bucket center alongside steady and balanced.

Scots kilt, Highland-pleated-skirt. As a color modifier, kilt implies a Highland-tartan-and-pleated-skirt quality, the visual register of Highland-tartan-and-Black-Watch-kilt hand-Highland-tartan-and-pleated-skirt Highland-tartan-and-Black-Watch-kilt-and-clan-Macleod kilt-and-Highland-tartan surfaces under Highland-tartan-and-Black-Watch-kilt-and-clan-Macleod Highland-clan-and-Edinburgh-tartan-mill tartan-and-pleated-light. Sits at the modifier-and-textile end of the grid, parallel to sash and tabard 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.
