Heroic Kihada

#819a06
Notes

Heroic Kihada (#819A06) is a deep yellow 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 (70°, 93%, 31%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

Kihada
noun

Phellodendron amurense, the Amur cork tree — and the bright yellow inner bark used as a Japanese textile dye and traditional medicine. Kihada-iro refers to the saturated yellow of kihada-dyed silk. The color refers to fresh kihada-bark powder: a saturated, slightly cool deep yellow with the matte finish of plant-derived pigment. Cooler than turmeric.

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.
