Poised Tarbuttite

#522e9f
Notes

Poised Tarbuttite (#522E9F) is a true indigo 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 (259°, 55%, 40%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Poised
adjective

Old French peser, to weigh — past-participle of poise. As a color modifier, poised implies a saturated-and-balanced-and-confident quality where the hue holds its position with elegant equilibrium. Sits at the bold-and-confident end of the grid, parallel to centered and composed.

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.
