Gloomy Hatoba

#4c2182
Notes

Gloomy Hatoba (#4C2182) is a deep indigo 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 (267°, 60%, 32%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gloomy
adjective

Middle English gloumen, to look glum — adjectival suffix -y. As a color modifier, gloomy implies a deep-and-cool-and-overcast quality, the dark cool-gray of Yorkshire-Moors and Scottish-Highlands late-autumn atmospheric-overcast sky. Sits at the deep-and-cool end of the grid, parallel to sullen and somber.

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.
