Serviceable Chrysocolla

#218f57
Notes

Serviceable Chrysocolla (#218F57) is a true teal 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 (149°, 63%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary magenta. 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.

Chrysocolla
noun

A copper-aluminum hydrous silicate — saturated blue-green, mined principally in copper-mineral deposits of Arizona, Israel, and the Democratic Republic of the Congo. The color refers to a polished chrysocolla cabochon: a saturated, slightly cool deep blue-green with the matte finish of secondary copper mineral. Cooler than malachite.

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.
