Bold Manhattan

#3772dc
Notes

Bold Manhattan (#3772DC) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (219°, 70%, 54%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

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.
