Alert Sign Triangle black filled icon

About the Alert Sign Triangle black filled icon

An equilateral triangle with softly rounded corners holding a centered exclamation mark whose stroke tapers from thick at the top to a point above a separate round dot. It is the universal shorthand for caution, error and important notice. Use it in form-validation messages, system error banners, safety signage, dashboard warnings and app permission dialogs.

The triangle sits on a flat base with generous inner margin, so the exclamation stays legible even when the icon is scaled down to toolbar size. It pairs with info circle, error cross and success check icons for a full status set. Tint it amber in interfaces to separate warnings from hard errors.

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