Use cases

  • Background de-emphasis

    Blur or dim background imagery behind overlays so foreground content becomes clearer.

  • Media styling

    Adjust tone or emphasis on images and icons without editing the source asset.

Cautions

  • Blur and contrast changes can reduce legibility if applied to content-bearing elements.
  • Heavy filter effects may affect performance on large or animated elements.

Accessibility

  • Do not rely on filtered imagery as the only way to distinguish content states or convey meaning.
