Card Color Warp

You have a card selected and returned to somewhere in the middle of the pack. You explain that you will magically cause the card to slowly rise to the top of the deck. After muttering some magic phrases, you turn over the top card. It IS the spectator's card, but it's face has turned BLACK! You explain that sometimes, as the card is squeezing through the others, it undergoes a "color warp" The trouble is, you say, that this usually happens in threes. Turning the card over again, it is seen to have turned to green! "Remember," you say, "it usually happens in threes." Turning the card over once more, you show that its back has also now turned green!

(Bicycle Colored Cards included. Requires a little practice)
