Fiery Seaholly

#03b28d
Notes

Fiery Seaholly (#03B28D) 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 (167°, 97%, 35%) 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

Fiery
adjective

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.

Seaholly
noun

Eryngium maritimum, the European sea holly — a coastal-dune perennial with silver-blue spiny foliage and metallic-blue flower heads, persistent enough to weather Atlantic storms on exposed dune ridges. The color refers to fresh E. maritimum foliage: a soft, slightly cool silver-blue-green with the matte finish of waxy-cuticled coastal succulent.
