4 Color Blind by Guillaume Bienne

Let four spectators make hidden color choices, then watch their choices complete a drawing that matches your prediction exactly. With 4 Color Blind, Guillaume Bienne brings a direct, visual color-match effect to close-up, parlor, or stage without electronics.

Each spectator selects one of four markers with identical caps, then colors a portion of a small card. You can adapt the reveal to a drawing, letters that spell a word, or four cards that combine into one image.

• No electronics — Present the effect without relying on electronic devices or Bluetooth connections.
• Customizable predictions — Choose drawings, words, or a combined image to suit your performance.
• Multiple settings — Perform the routine close-up, in parlor settings, or on stage.
• Instant reset — Get ready to perform it again without a lengthy reset.
• Included instruction — Learn the handling through in-depth tutorial videos, including a live performance from the March 2024 Rendez Vous Convention.

The included tutorial features nearly an hour of explanations and routines, filmed with Guillaume’s partner Yoan Tanuji. Add a participatory mentalism moment to your set, then tailor the final image to the audience in front of you.
