Inky Verbena

#391c8b
Notes

Inky Verbena (#391C8B) 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 (256°, 66%, 33%) 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

Inky
adjective

An adjectival form of ink, used as a color modifier since the eighteenth century to suggest the deep saturated black of fresh writing ink seen against white paper. Less about literal blackness than about the optical density of a fluid that absorbs light through its full thickness. Used at the dark end of any saturated hue: an inky blue is a deep saturated blue with the optical depth of pigment in solution.

Verbena
noun

The cultivated genus Verbena — particularly Verbena × hybrida, the trailing bedding plant in the Verbenaceae family with violet-and-magenta flat-topped cymes used in Mediterranean container gardens. Verbena color refers to a fully bloomed Verbena bonariensis cyme: a saturated, slightly cool deep blue-violet with the velvet finish of dense small four-petaled flowers. Slightly cooler than Vervain and warmer than Liatris.

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.
