Decisive Foresta

#1b8700
Notes

Decisive Foresta (#1B8700) 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 (108°, 100%, 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

Decisive
adjective

From the Latin decidere, to cut off — used as a modifier for colors that read as firm and final. Decisive black, decisive red: the implication is that the color has settled on its position and won't drift. Sits in the bold-bucket corner alongside resolute, with a slightly sharper edge.

Foresta
noun

The Italian word for forest — used in the Foreste Casentinesi national park of Tuscany and the saturated deep green of Italian Alpine forests. The color refers to a Foreste canopy seen from above: a saturated, slightly cool deep green with the matte finish of mixed conifer-and-broadleaf foliage.

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.
