VARIATIONS by Boris Wild - Book

magician still manages to guess the two chosen cards.
Color Changing Chicago: A spectator names a card at random in a red deck spread face up. Without the slightest suspicious move, the magician turns the deck over and shows there is one and only one blue-backed card in the spread. He turns this card over in the clearest possible way: it is the named card. An indifferent card from the deck changes places with the spectator's card, thus becoming a blue-backed card while spectator's card becomes red again. Finally, the indifferent card becomes red again too and then the whole deck momentarily turns blue before getting back to red again like it was at the beginning.
Technique: The "Cull"
