Warning black filled icon

About the Warning black filled icon

A rounded-corner triangle holds a tapered exclamation mark with a separate square dot, and the whole sign sits centered inside a thin circular border. It is the universal caution marker, useful for form validation and error states in apps, system alert dialogs, road and construction signage, safety manuals and hazard labeling on equipment or packaging.

The circle-in-triangle nesting leaves generous breathing room, so the mark still reads at badge sizes, while the thinner outer ring keeps the triangle dominant. Use it beside info, error and success circle icons for a consistent status row, and reserve the filled style for critical alerts where the shape must stand out fast.

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