Notes
Bootstrap Danger is the red used for error alerts, destructive buttons, and validation warnings in Bootstrap 5. It is brighter and slightly cooler than the framework's red counterpart in the v4 release, tuned to maintain WCAG AA against white text at common button sizes. Because Bootstrap is still embedded in vast amounts of enterprise and admin software, this exact red has become a de facto convention for irreversible actions across the web. If your design system needs a destructive color, this hex is a defensible starting point. Neutral grays for type keep the red readable rather than alarming.
