Jazzed Mustard

#f39836
Notes

Jazzed Mustard (#F39836) 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 (31°, 89%, 58%) 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

Jazzed
adjective

American slang jazz, liveliness — past-participle of jazz. As a color modifier, jazzed implies a saturated-and-excited-and-active quality, the bright color of American-Jazz-Age poster-and-album-cover saturated-and-rhythmic graphic-design. Sits at the bright-and-active end of the grid, parallel to caffeinated and wired in usage.

Mustard
noun

The condiment ground from the seeds of Brassica nigra and Sinapis alba — cultivated in the Mediterranean and South Asia for at least four thousand years. The color refers to French Dijon-style prepared mustard: a warm, slightly muted gold-yellow with the dusty surface of a paste, deeper than honey and earthier than yolk. The seed itself ranges from pale tan to nearly black depending on species.
