Sunken Manhattan

#1e2988
Notes

Sunken Manhattan (#1E2988) 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 (234°, 64%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sunken
adjective

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.

Manhattan
noun

The New York borough — and the deep saturated blue of Manhattan Bridge steel-cable paint and the Manhattan Project atomic-research blue document folders. Manhattan color refers to a Manhattan Bridge cable freshly painted: a saturated, slightly cool deep blue with the matte finish of marine-grade enamel paint over rusted steel.

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.
