Handcrafted Asphalt

#100a3c
Notes

Handcrafted Asphalt (#100A3C) 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 (247°, 71%, 14%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Handcrafted
adjective

English compound hand + past-participle crafted. As a color modifier, handcrafted implies a neutral-and-hand-built-and-skilled quality, the neutral color of Mingei-Japanese and American-Craftsman-and-Arts-and-Crafts hand-built-and-quality-craft furniture-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to crafted and artisanal in usage.

Asphalt
noun

Bitumen mixed with crushed stone aggregate — the dominant paving surface of every road network from the late nineteenth century forward. The color refers to a fresh asphalt road on a sunny day: a soft, slightly muted dark gray with the matte finish of stone-and-tar surface. Warmer than slate, cooler than tarmac (its lighter cousin), with the infrastructural weight of a material that paves more square kilometers than any other pavement type.

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.
