"I was blindsided by this new edition and method. I love doing it and so will you. I use it now as a traveling piece of real mentalism. It is real thinking to the nth degree."

The original Blindsight has been one of the bestselling tricks in magic, having sold over 5000 copies. Here is a new improved version. The effect is the same, but the method has been improved.
Performer explains that Blindsight is the apparent ability to see colors and shapes that cannot be seen. You offer a simple experiment. You introduce 4 ungimmicked colored cards: red, blue, green, and yellow. These in turn are sealed into 4 opaque envelopes in full view and mixed so that the spectator doesn't know which color is in which envelope. You pick up an envelope and ask him what color he thinks is inside. Assume he says green. You write "green" on the envelope. This is repeated three more times with the remaining envelopes. Each time, he states the color he thinks is inside and the performer writes it on the envelope.
Performer fans the envelopes out, allowing the person to see the names written on each envelope. Magician states he only needs three envelopes for the first part and for the person to remove one envelope and place it off to the side. Let's assume he discards the envelope with the word "green" written on it.
The other three envelopes are opened one at a time -- the spectator has correctly guessed which colors were in each envelope! This is pretty amazing in itself but the kicker is still to come.
Magician says nobody could have known what envelope the spectator would discard off to the side. The spectator, not the magician, picks up this envelope and opens it. Of course the correct color card is in it, but wait; there is a slip of paper in it and it reads: "THE GREEN ENVELOPE WILL BE THE ONE YOU DISCARD!"
The magician can then show the other envelopes to be empty. Here are the facts:
