Twilit Kimono Ultramarine

#08175e
Notes

Twilit Kimono Ultramarine (#08175E) is a deep blue 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 (230°, 84%, 20%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Twilit
adjective

An adjectival form of twilight, coined in the late nineteenth century. Twilit describes a color seen at twilight — the slight cooling and desaturation that low ambient light introduces. Sits in the deep-and-cool corner, lighter than somber and bluer than shadowed. Almost exclusively literary.

Kimono
modifier

Japanese kimono, thing-to-wear. As a color modifier, kimono implies a Japanese-kimono-and-furisode-and-tomesode quality, the visual register of Edo-and-Heian-kimono-and-furisode hand-Japanese-kimono-and-furisode-and-tomesode Edo-and-Heian-kimono-and-furisode-and-Kyoto-Nishijin kimono-and-Japanese-kimono-and-furisode surfaces under Edo-and-Heian-kimono-and-furisode-and-Kyoto-Nishijin Heian-Kyoto-and-Edo-Tokugawa Japanese-court-light. Sits at the modifier-and-textile end of the grid, parallel to haori and sari in usage.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
