Defined Seaholly

#a8f9d6
Notes

Defined Seaholly (#A8F9D6) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (154°, 87%, 82%) places it in the highly saturated band at a light 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

Defined
adjective

Latin dēfīnīre, to set bounds — past-participle of define. As a color modifier, defined implies a clear-and-edge-distinct-and-precise quality where the hue carries the visual register of sharp-bounded-and-clearly-delimited surface. Sits at the crisp-and-clear end of the grid, parallel to crisp and sharp 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.
