Shaker Tarmac

#1b1c10
Notes

Shaker Tarmac (#1B1C10) is a deep yellow with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (65°, 27%, 9%) places it in the muted 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Shaker
adjective

English Shaker, United-Society-of-Believers-in-Christ's-Second-Appearing — adjectival usage of Shaker. As a color modifier, shaker implies a neutral-and-plain-and-stripped-down quality, the neutral color of Shaker-furniture-and-craft anti-ornamental-and-functional hand-built-and-precise-craft surface-finish. Sits at the neutral-and-stripped-down end of the grid, parallel to quakerly and plain in usage.

Tarmac
noun

A specific type of asphalt paving — tar macadam, named for John Loudon McAdam's 1820s road technique combined with tar binder. Tarmac in British English now means airfield runway generally. The color refers to a fresh runway surface: a soft, slightly muted dark gray with the matte finish of stone-and-bitumen paving. Lighter than asphalt, warmer than slate, with the aviation-and-road weight of an infrastructure word that traveled across the Atlantic.
