Engraved Tarbuttite

#a29bcb
Notes

Engraved Tarbuttite (#A29BCB) is a true blue 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 (249°, 32%, 70%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

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.

Tarbuttite
noun

Rare zinc-phosphate mineral first described from the Broken Hill lead-zinc deposits of Zambia in 1907, also found at Reaphook Hill in South Australia. Tarbuttite color refers to a deep-violet Broken Hill tarbuttite crystal cluster: a saturated, slightly cool deep blue-violet with the glassy finish of zinc-phosphate mineral. Named for Percy Coventry Tarbutt, an early-20th-century mining-company director.
