Gleaming Cotswold

#f3ad25
Notes

Gleaming Cotswold (#F3AD25) is a true amber 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 (40°, 90%, 55%) 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

Gleaming
adjective

The progressive participle of gleam, to shine intermittently. Used as a color word for hues with the slight optical motion of a polished or wet surface. Gleaming gold, gleaming red: the implication is luminance combined with the optical impression of specular highlight. Sits in the bright-and-glossy corner alongside lustrous.

Cotswold
noun

The English limestone-built region — and the warm honey-tan of Cotswold limestone used in the cottages and dry-stone walls of Gloucestershire and Oxfordshire. The color refers to a Cotswold cottage facade in afternoon sun: a soft, slightly muted warm tan with the matte finish of weathered porous stone. Drier than honey, warmer than sand.

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.
