Engraved Cataract

#407573
Notes

Engraved Cataract (#407573) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (178°, 29%, 35%) places it in the muted 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.

Cataract
noun

A large waterfall with significant volume — particularly the Cataracts of the Nile and the Iguaçu Cataract of South America. Cataract color refers to the deep blue-white of high-volume falling water at Iguaçu: a saturated, slightly cool deep blue-white with the optical brightness of micron-scale air-water mixing.
