What is a CMY Cube? CMY Cubes use primary colours Cyan, Magenta & Yellow (CMY) and are created to help view life & light through a different lens. A truly unique and interactive toy, the CMY Cubes will keep children and adults engaged and entertained for hours. Warning: The CMY Cubes are addictive! This fascinating cube appears to create an ever-changing spectrum of colour, providing you with endless enjoyment. Each face of the translucent cube is coated in electromagnetically subtractive materials which at first, appear as cyan, magenta, or yellow. With a twist and turn of the geometry, these seemingly primary colours magically transform into an array of colours. How many colours can you create? Designed in Australia.
