A warning stripe has very little time to earn attention. Safety Yellow answers that problem with a dense signal that remains legible at a glance.

Almost no blue—just 2—appears in #EED202. Red at 238 and green at 210 make the signal bright, with a slight turn toward gold.

Place it on equipment tags, temporary notices, or a route change in a dark map. Asphalt gives the clearest working contrast; navy adds a cool civic feel, and hazard red raises the urgency.
