Royal Kohaku

#892903
Notes

Royal Kohaku (#892903) 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 (17°, 96%, 27%) 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

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

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.

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.
