Buzzed Buttercup

#f0ce05
Notes

Buzzed Buttercup (#F0CE05) 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 (51°, 96%, 48%) 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

Buzzed
adjective

Imitative-onomatopoeic origin — past-participle of buzz, evoking the sound of bee-hum. As a color modifier, buzzed implies a saturated-and-vibrating-and-active quality, the bright color of insect-pollinator and neon-lamp low-amplitude-buzz visual-vibration. Sits at the bright-and-active end of the grid, parallel to jazzed and wired in usage.

Buttercup
noun

Ranunculus acris and its meadow cousins — the small, glossy yellow flowers of European pastures whose petals reflect ultraviolet light to attract bees. The color refers to a buttercup petal in full sun: a saturated, slightly cool yellow with the polished finish of an epidermis that scatters light like wet paint. The folk test for whether you like butter — holding the flower under your chin to catch its yellow reflection — works on every variety.

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.
