Serviceable Larimar

#63cffd
Notes

Serviceable Larimar (#63CFFD) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (198°, 97%, 69%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Serviceable
adjective

Latin servītium, service — adjectival suffix -able. As a color modifier, serviceable implies a clear-and-fit-for-purpose-and-durable quality where the hue carries the visual register of long-lasting-and-functional everyday-use design. Sits at the crisp-and-functional end of the grid, parallel to practical and utilitarian in usage.

Larimar
noun

A blue variety of pectolite — a calcium-sodium silicate — found only in one mountain range in the Dominican Republic. Marketed as a gemstone since the 1970s and named after a Spanish word for the sea. The color refers to a polished larimar cabochon: a soft, slightly muted light blue with the cloudy translucency of pectolite. Lighter than aqua, warmer than glacier, with the gem-trade specificity of a stone that occurs in exactly one place on Earth.

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.
