Pleasant Tooled Teal

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Old French tōl, implement. As a color modifier, tooled implies a hand-worked-and-detailed quality, the visual register of Renaissance-and-Florentine-tooled-leather hand-worked-and-stamped-and-engraved tooled-leather-and-bookbinding-and-saddle-and-belt hand-worked surfaces under Renaissance-and-Florentine hand-tooled-leather workshop-light. Sits at the modifier-and-texture end of the grid, parallel to carved and inlaid 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.
