Robust Glee Forest

#048015
Notes

Robust Glee Forest (#048015) 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°, 94%, 26%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Glee
modifier

Old English glēo, music-or-merriment. As a color modifier, glee implies a singing-and-merry-and-bubbling quality, the visual register of Elizabethan-glee-club-and-madrigal-glee hand-singing-and-merry-and-bubbling Elizabethan-glee-club-and-madrigal-and-catch-singing gleeful-and-singing-and-merry-and-bubbling surfaces under Elizabethan-glee-club-and-madrigal-and-catch-singing parlor-and-tavern-and-court candlelit-music-light. Sits at the modifier-and-mood end of the grid, parallel to mirth and merry 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.
