What is a CMY Cube?
Our 175,000+ customers describe it as "a mesmerising sensory toy for all ages."

Hold it to the light and watch cyan, magenta, and yellow mix into colours you didn't expect. The CMY Cube blends STEAM education with playful curiosity: real optics and physics you can turn over in your hands.

How does it work?
Each face of the optically clear acrylic cube is sealed with a subtractive colour filter. On their own the faces appear cyan, magenta, or yellow. Look through two or three at once and the filters stack, subtracting wavelengths from white light to create a whole spectrum of new colours. Twist, turn, and see the world through a different lens.

How many colours can you create?

Designed in Australia.

Safety: recommended for ages 12 and up.
