Plain Lovage Kingfisher

#099fb4
Notes

Plain Lovage Kingfisher (#099FB4) is a true cyan 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 (187°, 90%, 37%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plain
adjective

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

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.

Kingfisher
noun

The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.

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.
