Reposed Dumortierite

#586581
Notes

Reposed Dumortierite (#586581) is a true azure 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 (221°, 19%, 43%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reposed
adjective

Latin repōnere, to put back — past-participle of repose. As a color modifier, reposed implies a hushed-and-restful-and-still quality where the hue carries the visual register of pre-modern monastic Cistercian-Cloister meditative-and-still interior-architecture. Sits at the hushed-and-still end of the grid, parallel to restful and contemplative in usage.

Dumortierite
noun

An aluminum-borate-silicate mineral — saturated deep blue, mined principally in Madagascar, Brazil, and Nevada. Used as ornamental stone and porcelain manufacturing additive. The color refers to a polished dumortierite cabochon: a saturated, slightly cool deep blue with the matte finish of opaque silicate mineral.
