Cloaked Indigobird

#15303f
Notes

Cloaked Indigobird (#15303F) is a deep azure 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 (201°, 50%, 16%) 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.

Indigobird
noun

The genus Vidua — African parasitic finches whose males display saturated indigo-blue plumage in breeding season. The color refers to a male V. chalybeata (village indigobird) in breeding plumage: a saturated, slightly cool deep blue-violet with the iridescent satin finish of structural feather color.
