Assured Clove Ruby
Assured Clove Ruby (#852237) is a deep red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (347°, 59%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French aseürer, to give assurance — past-participle of assure. As a color modifier, assured implies a saturated-and-confident quality where the hue carries unwavering certainty about its own visual identity. Sits at the bold-and-confident end of the grid, parallel to certain and poised.
Latin clāvus, nail-shaped-aromatic-bud. As a color modifier, clove implies a warm-pungent-and-Indonesian-Spice-Island quality, the visual register of Indonesian-Spice-Island-and-Zanzibar-clove hand-warm-pungent-and-Indonesian-Spice-Island Indonesian-Spice-Island-and-Zanzibar-clove-and-Banda-Islands clove-and-warm-pungent-and-Indonesian-Spice-Island surfaces under Indonesian-Spice-Island-and-Zanzibar-clove-and-Banda-Islands Banda-Islands-and-Zanzibar-and-Maluku Spice-Islands-light. Sits at the modifier-and-flavor end of the grid, parallel to nutmeg and anise in usage.
From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.
