The cards aren't white on both sides, one side is already colored. The color looks paler under the colored light (just an illusion I believe) so it looks about the same as a white card palely colored bythe colored light. So he's flipping a card over to the colored side once it's under the colored light, the pale color makes it look a white card slightly colored by the light, and when he slides it out from under the light the full deep color is revealed. It's skilled card manipulation aided by the colored light.
