Hefty Spica Forest

#308821
Notes

Hefty Spica Forest (#308821) 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 (111°, 61%, 33%) 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Spica
modifier

Latin spīca, ear-of-grain. As a color modifier, spica implies a Virgin-and-grain-ear-and-blue-white-star quality, the visual register of Virgo-constellation-and-spring-Spica hand-Virgin-and-grain-ear-and-blue-white-star Virgo-constellation-and-spring-and-Bortle-1-sky spica-and-Virgin-and-grain-ear-and-blue-white-star surfaces under Virgo-constellation-and-spring-and-Bortle-1-sky April-and-May-spring-southern-vista grain-bearing-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to vega and altair 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.
