Sunken Aubrieta
Sunken Aubrieta (#143D9D) is a true azure 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 (222°, 77%, 35%) places it in the highly saturated band at a mid 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The past participle of sink — used as a color modifier since the eighteenth century for surfaces that read as receded or enclosed. Sunken implies a slightly cool darkness with the optical quality of a recessed plane: the sunken eye sockets of a sculpture, the depressed channels of an Anglo-Saxon enamel. Sits in the deep-and-cool corner, closer to shadowed than to brooding.
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.
