Cloaked Hawkseye

#0f3f50
Notes

Cloaked Hawkseye (#0F3F50) is a deep cyan 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 (196°, 68%, 19%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cloaked
adjective

Old French cloque, bell-cloak — past-participle of cloak. As a color modifier, cloaked implies a deep-fabric-shrouded quality where the hue is muffled by an enveloping textile-darkness. Sits at the deep-and-fabric end of the grid, parallel to mantled and hooded in usage.

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.
