Saturated Tourmaline
Saturated Tourmaline (#047027) is a deep green 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 (139°, 93%, 23%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Latin saturatus, past participle of saturare, to fill. A technical color term in modern usage — saturation is one of the three axes of HSL (with hue and lightness). As a modifier, saturated implies that the hue is at or near its maximum chromatic intensity. Sits at the bold-and-bright top of the grid.
A boron silicate mineral that crystallizes in nearly every color depending on its trace elements — green tourmaline (verdelite) is the chromium and vanadium-bearing variety, mined principally in Brazil, Madagascar, and Maine. The color refers to a faceted green tourmaline: a saturated, slightly muted blue-green with the high refractive index of a quality cut gem. Cooler than emerald, warmer than aquamarine.
