About the Error Warning Triangle black filled icon
A triangle with rounded corners is drawn twice, one outline inside the other, framing a thick exclamation mark with a separate round dot beneath it. The shape is the universal sign for a mistake, hazard or blocked action. Use it for form validation messages, failed payment and upload states, browser security warnings, road safety graphics and error screens in mobile apps.
The inner border sits close to the outer edge, giving the icon the weight of a printed hazard sign, while the exclamation stroke tapers slightly toward its base and stays centered. It matches check circle, info and ban icons in an alert set. At 16 px the double border can fill in, so use the single line version.
This is the solid black filled version of the error 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.
