Red Circle Symbol - Prohibition, Warning, and Design Element #3611443 (License: Personal Use)

This image shows a thick red circular border enclosing a white center, set against a muted green background. The design follows international standards for prohibition signs (e.g., ISO 7010), where a red circle with a diagonal slash indicates “not allowed.” In digital contexts, it’s often used as a UI indicator for errors, disabled actions, or alerts.

Used in traffic signage, safety manuals, software interfaces, and web design to signal restriction, error, or caution. Matches user intent for visual symbols related to warnings, UX feedback, or regulatory compliance.
