Cool Agora Teal

Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.

Greek agora, Greek-marketplace. As a color modifier, agora implies a Greek-and-Athens-marketplace quality, the visual register of Athenian-and-Spartan-Agora hand-built marketplace-and-civic-meeting-square agora-and-stoa-and-bouleuterion classical-Greek architectural surfaces under Athenian-Agora-and-Spartan-Lacedaemon classical light. Sits at the modifier-and-architecture end of the grid, parallel to forum and stoa 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.
