Folded Vivianite

#287a82
Notes

Folded Vivianite (#287A82) 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°, 53%, 33%) 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

Folded
adjective

Old English fealdan, to fold — past-participle of fold. As a color modifier, folded implies a clear-and-creased-and-arranged quality where the hue carries the visual register of carefully-folded-and-neatly-arranged textile surface. Sits at the crisp-and-finished end of the grid, parallel to pressed and trim in usage.

Vivianite
noun

A hydrated iron phosphate mineral — colorless when freshly exposed, oxidizing to deep blue-green within hours of air exposure. Mined principally in Cornwall and California. The color refers to a fully-oxidized vivianite specimen: a saturated, slightly cool deep blue-green with the slight metallic luster of phosphate mineral.
