Tough Berg Forest

#2f9429
Notes

Tough Berg Forest (#2F9429) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (117°, 57%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Tough
adjective

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.

Berg
modifier

Norwegian isberg, mountain-of-ice. As a color modifier, berg implies an iceberg-and-Antarctic-tabular-ice quality, the visual register of Antarctic-and-Greenland-iceberg hand-iceberg-and-Antarctic-tabular-ice Antarctic-and-Greenland-iceberg-and-Larsen-Ice-Shelf berg-and-iceberg-and-Antarctic-tabular-ice surfaces under Antarctic-and-Greenland-iceberg-and-Larsen-Ice-Shelf Ross-Sea-and-Weddell-Sea-and-Disko-Bay tabular-iceberg-light. Sits at the modifier-and-weather end of the grid, parallel to floe and icicle 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.
