Over This World by Alex Pandrea
A shuffled deck is handed to the spectator. They remove a card from anywhere in the deck. Without looking at, or touching the cards the magician is able to name the color of the card. This is repeated as many times as you wish. The magician then starts to separate all the black cards from all the red cards without looking at the deck. For the finale, the deck is shuffled again and now the spectator separates the colors in their hands.
