Authoritative Cumin Ruby

#a71225
Notes

Authoritative Cumin Ruby (#A71225) 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 (352°, 81%, 36%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Cumin
modifier

Greek κύμινον, aromatic-Levantine-seed. As a color modifier, cumin implies a warm-Levantine-and-North-African-and-Mughal quality, the visual register of Levantine-and-North-African-and-Mughal-cumin hand-warm-Levantine-and-North-African-and-Mughal Levantine-and-North-African-and-Mughal-cumin-and-Aleppo-and-Marrakesh cumin-and-warm-Levantine surfaces under Levantine-and-North-African-and-Mughal-cumin-and-Aleppo-and-Marrakesh Aleppo-and-Marrakesh-and-Lahore Levantine-spice-light. Sits at the modifier-and-flavor end of the grid, parallel to caraway and pepper 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.
