Central Licorice

#1a0017
Notes

Central Licorice (#1A0017) is a deep violet 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 (307°, 100%, 5%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Central
adjective

Latin centrālis, central — adjectival suffix -al. As a color modifier, central implies a neutral-and-central-and-balanced quality where the hue carries the visual register of Mid-Century-Modern and Bauhaus central-and-balanced-and-grounded foundational-design fundamental-element. Sits at the neutral-and-foundational end of the grid, parallel to core and grounded in usage.

Licorice
noun

Glycyrrhiza glabra, the Mediterranean legume whose root yields glycyrrhizin — fifty times sweeter than sugar and the basis of European black licorice candy. The color refers to a fresh stick of black licorice candy: a deep, slightly muted near-black with the slight shine of a starch-bound confection. Warmer than ink, glossier than soot, with the candy-jar weight of a flavor and color identified almost entirely with one root extract.
