About the Alert Warning Triangle black filled icon
An upward triangle with softly rounded corners holds a vertical stroke above a short dot, forming a centered exclamation mark. It is the standard shape for caution, so it reads correctly without a caption in any language. Apply it to form validation errors, system and browser warning dialogs, hazard labels on packaging, machinery safety plates and roadside or construction site notices.
The triangle is close to equilateral with generous inner margin, and the exclamation stroke is thick enough to stay solid when the whole mark is scaled down to toolbar size. It pairs with the info, error circle and question mark icons in the library. Keep the surrounding padding clear so the corners stay sharp.
This is the solid black filled version of the alert warning triangle icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
