Fiery Tourmaline
Fiery Tourmaline (#0FB898) is a true teal 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 (169°, 85%, 39%) 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
Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.
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.
