Heritage Hawkseye

#3d5859
Notes

Heritage Hawkseye (#3D5859) is a deep cyan 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 (182°, 19%, 29%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heritage
adjective

Latin hereditas, inheritance — used as a color modifier since the late twentieth century for hues that read as drawn from historical palettes. Heritage green, heritage red: moderate-to-low saturation combined with the optical impression of paint formulated to match a specific historical period. Sits at the hushed-bucket alongside antique.

Hawkseye
noun

A blue-gray variety of tigereye quartz — colored by crocidolite asbestos inclusions that scatter light into a chatoyant band like the eye of a raptor. The color refers to a polished Hawkseye cabochon: a soft, slightly cool deep blue-gray with the optical complexity of chatoyant silicate fibers.
