Unyielding Lovage Ruby

#900417
Notes

Unyielding Lovage Ruby (#900417) is a deep 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°, 95%, 29%) places it in the highly saturated band at a dark 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

Unyielding
adjective

Old English un- (negation) plus gildan (to give-up). As a color modifier, unyielding implies a saturated-and-uncompromising quality where the hue refuses to fade-or-shift under any visual pressure. Sits at the bold-and-resilient end of the grid, parallel to indomitable and adamant in usage.

Lovage
modifier

Latin levisticum, medieval-physic-garden-herb. As a color modifier, lovage implies a medieval-physic-garden-and-celery-leaf quality, the visual register of medieval-physic-garden-and-Cluniac-lovage hand-medieval-physic-garden-and-celery-leaf medieval-physic-garden-and-Cluniac-lovage-and-Benedictine-Saint-Gall lovage-and-medieval-physic-garden-and-celery-leaf surfaces under medieval-physic-garden-and-Cluniac-lovage-and-Benedictine-Saint-Gall Cluny-and-Saint-Gall-physic-garden medieval-monastic-light. Sits at the modifier-and-flavor end of the grid, parallel to savory and catnip 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
