Thunderous Lovage Ultramarine

#071651
Notes

Thunderous Lovage Ultramarine (#071651) is a deep blue 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 (228°, 84%, 17%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Thunderous
adjective

Old English thunor, thunder — adjectival suffix -ous, sharing root with German Donner and Old Norse Þórr (Thor). As a color modifier, thunderous implies a deep-and-rumbling-and-imposing-cool quality, the dark cool-gray of cumulonimbus-tower-base storm-cloud directly overhead. Sits at the deep-and-turbulent end of the grid, parallel to stormy with auditory-resonance overtone.

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.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

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.
