Sterile Lovage Lagoon

#0bb1ae
Notes

Sterile Lovage Lagoon (#0BB1AE) 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 (179°, 88%, 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

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic 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.

Lagoon
noun

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.

WCAG contrast

The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.

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.
