Warning Sign black filled icon

About the Warning Sign black filled icon

A filled triangle with softened corners carries a knocked-out exclamation mark, the standard shape for caution across road signs, machinery labels and software. It reads as danger, attention required and error. Use it for form validation and error states, system alert banners, destructive-action confirmations, safety instructions and manuals, and hazard labels on packaging or equipment.

The triangle is slightly wider than it is tall, which keeps it stable, and the exclamation stroke tapers toward its base above a round dot for a classic sign look. The solid fill gives strong contrast. Use it beside info and success status icons; at 16 px the silhouette alone still communicates.

This is the solid black filled version of the warning sign icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
