Refreshing Tourmaline

#3c7a4a
Notes

Refreshing Tourmaline (#3C7A4A) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (134°, 34%, 36%) 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

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Tourmaline
noun

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.

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.
