Native Korogi

#1d022a
Notes

Native Korogi (#1D022A) is a deep violet 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 (281°, 91%, 9%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Native
adjective

Latin nātīvus, born / natural — adjectival suffix -ive. As a color modifier, native implies a neutral-and-original-and-indigenous quality, the neutral color of Native-American and Aboriginal-Australian indigenous-and-original earth-and-mineral-pigment ceremonial-craft tradition. Sits at the neutral-and-traditional end of the grid, parallel to indigenous and aboriginal in usage.

Korogi
noun

Japanese 蟋蟀, cricket — particularly the Velarifictorus mikado (emma korogi, Emma cricket) of Japanese gardens whose deep-glossy-black exoskeleton and autumn-night call is a stock motif in classical waka poetry. Korogi color refers to a Velarifictorus mikado head-and-thorax in raking light: a saturated, slightly cool deep black with the glossy finish of melanin-and-chitin exoskeleton on the cricket's foreleg-stridulation organ.
