Submerged Indigobird

#123a3e
Notes

Submerged Indigobird (#123A3E) 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 (185°, 55%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Submerged
adjective

Latin sub-mergere, to plunge under — past-participle of submerge. As a color modifier, submerged implies the cool, deep, slightly-shifted quality of a hue viewed through a layer of water or glass. Sits at the deep-and-cool end of the grid, parallel to drowned and sunken 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.
