Warm Tarmac

#1b1306
Notes

Warm Tarmac (#1B1306) is a deep amber 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 (37°, 64%, 6%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

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.
