Smoky Patchouli

#40135a
Notes

Smoky Patchouli (#40135A) is a deep indigo 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 (278°, 65%, 21%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

Patchouli
noun

Asian Pogostemon cablin — an evergreen mint-family shrub native to Southeast Asia, cultivated for its essential-oil aromatic-leaf trade and bearing dense spikes of pale-violet labiate flowers. Patchouli color refers to a fully bloomed Pogostemon cablin spike on an Indonesian shamrock-leaf shrub: a saturated, slightly cool deep violet with the matte finish of dense small two-lipped patchouli corollas. The English name comes from the Tamil paccuḷ.
