Unblemished Kogane

#90720b
Notes

Unblemished Kogane (#90720B) is a deep amber 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 (46°, 86%, 30%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Unblemished
adjective

Old French blesmir, to wound — negative-prefix un- plus past-participle of blemish. As a color modifier, unblemished implies a clear-and-flawless quality where the hue carries no defect or imperfection. Sits at the crisp-and-clean end of the grid, parallel to pristine and spotless in usage.

Kogane
noun

The Japanese word for gold — used since the Heian period for the gilt highlights in Buddhist sculpture, the gold leaf of byōbu folding screens, and the kintsugi repair of broken ceramics. The color refers to fresh gold leaf on lacquer: a saturated, slightly cool deep gold-yellow with the metallic finish of beaten gold. Cooler than honey, deeper than yamabuki.
