Stark Hawkseye

#25464a
Notes

Stark Hawkseye (#25464A) 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 (186°, 33%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stark
adjective

Old English stearc, stiff / strong — sharing root with German stark and Dutch sterk. As a color modifier, stark implies a deep-and-uncompromising contrast where the hue stands without modulation against its substrate. Sits at the deep-and-formal end of the grid, parallel to severe with sharper visual register.

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.
