Steeped Manhattan

#1639a0
Notes

Steeped Manhattan (#1639A0) is a true 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 (225°, 76%, 36%) 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

Steeped
adjective

Old English stēpan, to dip / soak — past-participle of steep. As a color modifier, steeped implies the deep-and-saturation-rich quality of dye-bath-saturated textile, where the hue has reached fiber-saturation. Sits at the deep-and-saturated end of the grid, parallel to infused and suffused.

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.
