Frenetic Tabacco

#ac9519
Notes

Frenetic Tabacco (#AC9519) is a true amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (51°, 75%, 39%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Frenetic
adjective

Greek phrenitikós, frenzied — adjectival suffix -ic, derived from phrēn (mind). As a color modifier, frenetic implies a saturated-and-frenzied-and-active quality, the bright color of Hyper-Color-and-Memphis-Group 1980s-design saturated-and-active visual-rhythm. Sits at the bright-and-active end of the grid, parallel to frantic and manic in usage.

Tabacco
noun

The Italian word for tobacco — borrowed as a fashion color for the warm brown of cured tobacco leaves and the leather goods made in Tuscany. The color refers to a fresh-cured Italian tobacco leaf: a soft, slightly muted warm brown with the matte finish of dried plant material. Cooler than caramel, warmer than walnut.
