Prohibition Symbol - Red Circle with X Icon for Error or Denial #3436048 (License: Personal Use)

This image displays a standard prohibition icon-a solid red “X” centered within a red circular border-set against a transparent checkerboard background, indicating transparency support. The design follows international conventions for warning or denial, commonly used in user interfaces, safety signage, and error messaging. Its high-contrast red color ensures visibility and immediate recognition.

Used in web forms, mobile apps, and software to denote failed actions, invalid inputs, or prohibited operations; also appears in traffic signs, safety manuals, and regulatory documentation where visual negation is required.
