Flashing Sriracha

#f37d03
Notes

Flashing Sriracha (#F37D03) 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°, 98%, 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Flashing
adjective

Old English flasch, flash — present-participle of flash. As a color modifier, flashing implies a saturated-and-rapid-on-off quality, the bright color of emergency-vehicle and photographic-flash light-burst surfaces. Sits at the bright-and-flashing end of the grid, parallel to coruscating and flickering in usage.

Sriracha
noun

The Thai chili-garlic sauce — named for the coastal town of Si Racha, popularized worldwide by Huy Fong's California-made rooster sauce. The color refers to a fresh-shaken bottle of Sriracha: a saturated, slightly red deep orange with the slight viscosity of vinegar-and-pepper paste. Warmer than tabasco.
