Twilit Aubrieta

#182988
Notes

Twilit Aubrieta (#182988) is a deep blue 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 (231°, 70%, 31%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Twilit
adjective

An adjectival form of twilight, coined in the late nineteenth century. Twilit describes a color seen at twilight — the slight cooling and desaturation that low ambient light introduces. Sits in the deep-and-cool corner, lighter than somber and bluer than shadowed. Almost exclusively literary.

Aubrieta
noun

The genus Aubrieta — Mediterranean rock-garden perennial named for the eighteenth-century French botanical illustrator Claude Aubriet. Mauve-and-blue mat-forming spring bloomer. The color refers to a fresh A. deltoidea mat at peak bloom: a saturated, slightly cool deep blue-violet with the matte finish of small four-petaled flowers covering rocks.

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.
