Two discs, each black on one side and white on the other, are shown to a spectator. The two discs then come into contact with each other and are instantly transformed into multi-coloured discs: yellow, red, green, and blue. The black and white sides have become coloured! The discs are then handed to the spectator to be examined.

Comes complete with special discs, carrying pouch, detailed instructions, and everything else needed to perform this truly colourful and inventive illusion.
