Mapped Lurk Teal

#12b19a
Notes

Mapped Lurk Teal (#12B19A) is a true teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (171°, 82%, 38%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

Lurk
modifier

Middle English lurken, to-lie-hidden. As a color modifier, lurk implies a hidden-and-watching-and-shadowed quality, the visual register of forest-edge-and-alley-mouth-lurk hand-hidden-and-watching-and-shadowed forest-edge-and-alley-mouth-and-bridge-undercroft lurked-and-hidden-and-watching-and-shadowed surfaces under forest-edge-and-alley-mouth-and-bridge-undercroft Gothic-novel-and-fairy-tale-and-noir half-light. Sits at the modifier-and-mood end of the grid, parallel to creep and prowl in usage.

Teal
noun

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
