Bright Kihada

#a6b10a
Notes

Bright Kihada (#A6B10A) is a true 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 (64°, 89%, 37%) places it in the highly saturated band at a mid 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

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

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.
