Cool Merry 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.

Old English myrige, pleasant-and-glad. As a color modifier, merry implies a glad-and-bright-and-festive quality, the visual register of Robin-Hood-Merry-Men-and-Maytime-merry hand-glad-and-bright-and-festive Robin-Hood-Merry-Men-and-Maytime-and-village-fair merried-and-glad-and-bright-and-festive surfaces under Robin-Hood-Merry-Men-and-Maytime-and-village-fair Sherwood-Forest-and-Mayday-and-Whitsun greenwood-festival-light. Sits at the modifier-and-mood end of the grid, parallel to jolly and blithe 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.
