Assured Chive Ruby

#9c151f
Notes

Assured Chive Ruby (#9C151F) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (356°, 76%, 35%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Assured
adjective

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.

Chive
modifier

Latin cepa, small-onion-grass-herb. As a color modifier, chive implies a slim-grass-onion-and-spring-fresh quality, the visual register of English-cottage-garden-and-French-bistro-chive hand-slim-grass-onion-and-spring-fresh English-cottage-garden-and-French-bistro-chive-and-fines-herbes chive-and-slim-grass-onion surfaces under English-cottage-garden-and-French-bistro-chive-and-fines-herbes Sussex-cottage-and-Lyon-bouchon spring-onion-light. Sits at the modifier-and-flavor end of the grid, parallel to dill and chervil in usage.

Ruby
noun

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.
