RGB split effect for images

RGB Split shifts the red and blue channels horizontally in opposite directions while keeping green aligned. Bright edges develop colored fringes, giving lettering and photographs a misregistered glitch-art look.

Compare the edge of a bright letter with a flat background: the letter gains colored fringes while the background changes much less.

Creative applications

  • Add colored fringes to a digital poster headline.
  • Give a portrait or cover image a restrained broken-signal treatment.

Starting workflow

  1. Open the demo and choose a PNG, JPG, or WebP containing your artwork. RGB Split starts at its current default.
  2. Lower Amount for a narrow fringe, then increase it until the red and blue edges are distinct.
  3. Inspect the smallest lettering at its intended viewing size before exporting the image.

Key controls

Practical tips

  • Prepare poster lettering in your source image before bringing it into the browser demo.
  • Use modest separation for faces; larger offsets can turn small details into overlapping shapes.
  • Switch Animate off and keep playback paused to judge Amount without movement.

Limitations

  • Channel displacement is horizontal; this effect has no separate vertical or per-channel position controls.
