Defined Haori Peacock

#277d78
Notes

Defined Haori Peacock (#277D78) 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 (177°, 52%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Defined
adjective

Latin dēfīnīre, to set bounds — past-participle of define. As a color modifier, defined implies a clear-and-edge-distinct-and-precise quality where the hue carries the visual register of sharp-bounded-and-clearly-delimited surface. Sits at the crisp-and-clear end of the grid, parallel to crisp and sharp in usage.

Haori
modifier

Japanese haori, short-jacket-over-kimono. As a color modifier, haori implies a Japanese-haori-and-short-jacket-over-kimono quality, the visual register of Edo-and-Meiji-haori-jacket hand-Japanese-haori-and-short-jacket-over-kimono Edo-and-Meiji-haori-jacket-and-Kyoto-Nishijin-and-Tokyo-Asakusa haori-and-Japanese-haori-and-short-jacket surfaces under Edo-and-Meiji-haori-jacket-and-Kyoto-Nishijin-and-Tokyo-Asakusa Edo-Tokugawa-and-Meiji-Tokyo Japanese-jacket-light.

Peacock
noun

Pavo cristatus, the Indian peafowl whose male displays the most elaborate sexual ornament in birds — a fan of two-meter eyespotted tail feathers in iridescent blue-green. The color is structural, not pigmented: created by interference patterns in the feather barbules. Peacock blue refers to the dominant body color: a saturated, slightly muted teal-blue with the optical depth of structural color. Cooler than persian, warmer than sapphire.
