Crisp, brighter orange-red lane for urgent charts
About 100 Mph
100 Mph is the one that actually commits to red. It's deeper and less bright than Chef's Kiss, which means it won't ping every notification on your screen, but it's also more saturated than Bloody Salmon, so it doesn't soften into rust or retreat into wine territory. This is orange that leans hard into its red undertone, it sits closer to anger than playfulness, the kind of color that reads as urgent without feeling panicked.
Reach for it in alerts, error states, and real-time dashboards where you need designers and users to actually pause. Live warnings in financial apps, critical status badges, destructive action confirmations. It works on white backgrounds without flattening, and it holds steady against warm palettes because that red foundation keeps it from getting swallowed. Unlike Chef's Kiss' responsiveness or Autumn Fire's balanced energy, this one has weight. It announces something changed, and not in a good way.
Pair it with cool grays or clean whites and it lands exactly where warnings should live. Put it on warm backgrounds and it gets louder, which defeats the point, test early if your palette is already leaning orange.
