Hot Foglia

#3aab12
Notes

Hot Foglia (#3AAB12) is a true 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 (104°, 81%, 37%) places it in the highly saturated band at a mid 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

Hot
adjective

Old English hāt, of high temperature — applied metaphorically to color since the eighteenth century for warm hues at high saturation. Hot pink, hot red: the implication is luminous intensity combined with thermal warmth. Sits in the bright-and-warm corner of the grid, alongside burning and vivid.

Foglia
noun

The Italian word for leaf — used in art vocabulary for foglia d'oro (gold leaf), foglia secca (dried leaf), and the verde foglia of fresh foliage. The color refers to a fresh basil leaf in an Italian kitchen: a saturated, slightly cool green with the satin finish of fresh herb leaf. The Italian cousin of frond.
