Radiant Cuoio

#fbb04b
Notes

Radiant Cuoio (#FBB04B) is a true orange with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (34°, 96%, 64%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Radiant
adjective

From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.

Cuoio
noun

The Italian word for leather — used in fashion vocabulary for the warm brown of vegetable-tanned cowhide. Cuoio-color is the standard for Italian saddle and shoe leather. The color refers to a freshly oiled vegetable-tanned cuoio: a warm, slightly muted brown with the satin finish of finished leather. The Italian cousin of tan and cognac.
