Engraved Glauque

#18aba0
Notes

Engraved Glauque (#18ABA0) is a true cyan 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 (176°, 75%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Engraved
adjective

Old French engraver, to dig in — past-participle of engrave. As a color modifier, engraved implies a clear-and-precisely-cut quality, the crisp color of Albrecht-Dürer-and-Hogarth hand-pulled engraving-print fine-line incised-image. Sits at the crisp-and-incised end of the grid, parallel to etched and inscribed in usage.

Glauque
noun

The French adjective for gray-blue-green — borrowed from the Greek glaukos, the epithet of the goddess Athena's eyes (glaukōpis). Used in French color vocabulary for the cold gray-blue of stormy seas and aged metal patina. The color refers to a cold Atlantic morning at Pointe du Raz: a soft, slightly cool deep gray-blue-green.

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.
