Drained Riebeckite

#394364
Notes

Drained Riebeckite (#394364) is a deep blue 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 (226°, 27%, 31%) places it in the muted 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

Drained
adjective

Old English drēahnian, to filter — past-participle of drain. As a color modifier, drained implies a deep-and-emptied-and-pallid quality where the hue's vital warmth has been removed. Sits at the deep-and-cool end of the grid, parallel to deathly with desaturation overtone.

Riebeckite
noun

A sodium-iron amphibole — the source of crocidolite (blue asbestos) and the chatoyant inclusions in hawk's-eye quartz. Mined principally in South Africa and Australia. The color refers to a freshly cleaved riebeckite specimen: a deep, slightly cool dark blue-gray with the slight metallic shine of amphibole.
