Warning black outline icon

About the Warning black outline icon

A rounded triangle drawn with a double outline surrounds a bold exclamation mark and dot, the universal symbol for caution. It signals errors, hazards, risky actions or important notices that need attention. Use it for form validation messages, error banners, safety signage, road warning signs, app alerts and dashboard status indicators.

The thick double border gives the triangle extra visual weight so it reads clearly at small sizes. It pairs well with error, alert and notice icons in the set. Keep it at 24px or larger so the exclamation mark stays legible.

This is the black outline version of the warning icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
