Scarlet

Scarlet reads like a freshly painted fire door, not a candy flare or a fruitier cherry. It's a straight, high-saturation red-orange that hits hotter and cleaner than Maraschino's ripe punch, and it stays more assertively "red" than Red Riding Hood. Compared to Red Stop, Scarlet feels warmer and more energized, less strict and controlled.

I use the one you reach for when you want urgency that still feels crisp on light UI. Dashboards and finance apps are the sweet spot, especially incident callouts, threshold alerts, and high-priority queue badges in logistics and shipping control screens. It also works well for production QA markers and lab/warehouse status labels where you need to glance and know it matters, fast.

Pair it with near-whites or cool grays so it keeps its edge. On very warm backgrounds it can start to look a bit loud, so give it contrast and don't crowd it with other hot tones.
