Fresh Kohaku

#8b320b
Notes

Fresh Kohaku (#8B320B) is a deep orange 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 (18°, 85%, 29%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Kohaku
noun

The Japanese name for amber — fossilized tree resin imported from Baltic deposits since the Heian period and worked into ornamental beads, sword fittings, and netsuke. Also the name of a koi cultivar with red markings on white. The color refers to a polished Baltic-amber bead in a Japanese tea-ceremony display: a warm, slightly translucent gold-orange with the depth of resin. Cooler than honey, deeper than tangerine.
