Warning Icon - High-Contrast Alert Symbol for Web and UI Design #1491335 (License: Personal Use)

This vector-style warning icon uses a solid black circular frame with a centered white exclamation mark to convey urgency or caution. The background features evenly spaced diagonal stripes, enhancing contrast and visibility across light and dark themes. Optimized for scalability, it maintains sharp edges at any resolution and supports WCAG-compliant contrast ratios.

Used in web applications, error modals, safety instructions, and system alerts where immediate user attention is required; matches intent for “warning icon,” “alert symbol,” or “caution graphic” searches.
