Drowned Cobalto

#12277f
Notes

Drowned Cobalto (#12277F) is a deep blue 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 (228°, 75%, 28%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drowned
adjective

The past participle of drown — used as a color word principally in literary contexts for the dark blue-green of deep water and the muted browns of waterlogged earth. Drowned implies darkness with the optical complexity of a fluid medium absorbing and scattering light. Sits in the deep-and-cool quadrant, near sunken.

Cobalto
noun

The Italian word for cobalt — used for the saturated deep blue of cobalto-glaze on Tuscan and Venetian Renaissance ceramics. The color refers to a cobalto-glazed Tuscan piatto: a saturated, slightly cool deep blue with the high gloss of cobalt-glazed porcelain. The Italian cousin of cobalt.
