Heroic Tabard Forest

#135d0d
Notes

Heroic Tabard Forest (#135D0D) 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 (116°, 75%, 21%) 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

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

Tabard
modifier

Old French tabart, herald's-or-knight's-surcoat. As a color modifier, tabard implies a herald's-tabard-and-knight's-surcoat quality, the visual register of medieval-herald's-and-knight's-tabard hand-herald's-tabard-and-knight's-surcoat medieval-herald's-and-knight's-tabard-and-College-of-Arms tabard-and-herald's-tabard surfaces under medieval-herald's-and-knight's-tabard-and-College-of-Arms College-of-Arms-and-Bayeux-Tapestry heraldic-tabard-light. Sits at the modifier-and-textile end of the grid, parallel to kilt and cape 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.
