Smoky Brooklyn

#151c5a
Notes

Smoky Brooklyn (#151C5A) 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°, 62%, 22%) 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

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

Brooklyn
noun

The New York borough — and the deep blue of Brooklyn Bridge granite anchors-and-steel-cable assembly seen against East River water. Brooklyn refers to Brooklyn Bridge against late-evening city light: a saturated, slightly cool deep blue with the optical complexity of historic stone-and-cable bridge against urban-illuminated water.
