Inspired by runway fashion trends, these decks feature a nautical theme reinvented; a unique and classic card back design with a modern edge. The original card back incorporates fantastic nautical chart details like the central diamond shape, compass insignias, sun dial-inspired corner elements, and much more! Influenced by the beaming colors and patterns shown during Fashion Week, these decks show radiant red and blue hues in intricate and classic designs.

Bicycle® Mariner playing cards are available in red and blue. Hearts and Diamond suits are red or blue to match the deck color. Spades and Clubs suits are black in both the red and blue decks.

I was going to ask about blue colored hearts and diamonds as gaffs but the Mariner deck will do the job for the chameleon card effect. Use a heart or diamond card from the blue backed deck. Then when the chameleon absorbs the blue ink both the back and the face red colors have appeared to turn blue -- much more effective I think !
