Bastioned Brine Forest

#0c9130
Notes

Bastioned Brine Forest (#0C9130) 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 (136°, 85%, 31%) 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

Bastioned
adjective

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Brine
modifier

Old English brȳne, salt-water-or-pickle-brine. As a color modifier, brine implies a salt-water-and-pickle-and-tide-pool quality, the visual register of Atlantic-tide-pool-and-pickling-brine hand-salt-water-and-pickle-and-tide-pool Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool brine-and-salt-water-and-pickle surfaces under Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool Lizard-Point-and-North-Cornish-coast salt-tide-pool-light. Sits at the modifier-and-weather end of the grid, parallel to floe and torrent in usage.

Forest
noun

The dense canopy of a temperate or tropical woodland — oak, beech, pine, eucalyptus, mahogany — wherever leaves close above to filter the light below. Forest green refers to the average reflectance of a healthy mid-summer canopy seen from below: a saturated, slightly muted green with the matte finish of layered chlorophyll. Deeper than fern, cooler than olive, with the ecological weight of a word that has named every wooded biome on Earth.

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.
