Buried Hatoba

#641b68
Notes

Buried Hatoba (#641B68) is a deep violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (297°, 59%, 26%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buried
adjective

Old English byrgan, to inter — past-participle of bury. As a color modifier, buried implies the deep-shrouded darkness of a sealed-and-covered hue, where surface qualities are obscured by intervening material. Sits at the deep-and-obscured end of the grid, parallel to cloaked and entombed.

Hatoba
noun

Japanese 鳩羽, pigeon-wing (鳩羽色, hatobane-iro) — the deep iridescent blue-violet of the Streptopelia orientalis (Eastern Turtle Dove) breast plumage, named in the Heian Engishiki (927 CE) as a courtly color. Hatoba color refers to a Streptopelia orientalis breast feather: a saturated, slightly cool deep violet with the iridescent satin finish of structurally colored feather barbs.
