Sturdy Prow Forest

#148a23
Notes

Sturdy Prow Forest (#148A23) 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 (128°, 75%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

Prow
modifier

Old French proue, ship's-front. As a color modifier, prow implies a ship's-front-and-figurehead quality, the visual register of Royal-Navy-and-Tall-Ship-Prow hand-carved ship's-front-and-figurehead prow-and-cutwater-and-bowsprit maritime-architecture surfaces under tall-ship-prow-and-figurehead maritime-headway light. Sits at the modifier-and-nautical end of the grid, parallel to bow and hull 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.
