Yes, such a deck exists. I know this because I have one. I don't know what it is called, and I don't know where I got it, I think it was given to me by somebody who wanted to market the effect and wanted my opinion. It was really good. I'll give the description and it may help in your search.
shuffle the deck of blue backed cards, show the faces mix them up again if you like. have one card selected. Fan the cards and all the cards now match the selected card. But wait! Their card is different it is the only red card in a blue backed deck! But wait! Turn the cards over and spread the deck and all the backs are now red. Each time the cards are fanned or spread on the table.
