Inscribed Age Teal

#66dbfc
Notes

Inscribed Age Teal (#66DBFC) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (193°, 96%, 69%) 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

Inscribed
adjective

Latin īnscrībere, to write upon — past-participle of inscribe. As a color modifier, inscribed implies a clear-and-text-or-pattern-cut quality, the crisp color of Roman-Imperial-period monumental-stone inscription-and-monumental-text incised-relief. Sits at the crisp-and-incised end of the grid, parallel to etched and engraved in usage.

Age
modifier

Old French aage, period-of-life. As a color modifier, age implies a long-passage-of-time quality, the visual register of Bronze-and-Iron-and-Stone-Age multi-millennia archaeological-period age-and-epoch-marked surfaces under multi-millennia age-and-epoch-defining time-deep light. Sits at the modifier-and-time end of the grid, parallel to era and eld 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
