Red X Icon - Error, Cancel, or Prohibition Symbol for Web and UI Design #190796 (License: Personal Use)

This image features a clean, geometric red 'X' formed by two thick diagonal bars intersecting at the center against a solid black background. The stark contrast ensures maximum visibility and immediate recognition across devices and accessibility settings. It's a standard visual cue in user interfaces for rejecting actions, closing dialogs, or signaling invalid input.

Used in web and app UIs for error messages, close buttons, form validation feedback, and prohibition signage; matches user intent to understand warnings, dismiss actions, or recognize restricted operations.
