Explore subtractive colour mixing with the CMY cube.Opposing sides are coloured cyan, magenta or yellow. Rotating the angle from which the cube is viewed, varies the degree to which specific frequencies of cyan, magenta, and yellow are filtered from white light, resulting in a unique, cube-specific spectrum of colours. This process is called "subtractive colour mixing".

The internal geometry of the solid shape has an intermediate level of reflectance over the visible light spectrum. This means that when white light reaches a face of the cube, a portion of that light passes through the face, while the remaining light is either reflected or absorbed. Light reflecting off of the outside faces of the cube is what gives us the cyan, magenta, and yellow colours of the spectrum while the material coating each face absorbs the other frequencies. The light that passes through the material retains only the band of frequencies not otherwise absorbed.

When this passed-through light makes contact with a different face pair, the process repeats, this time the material absorbs a different band of frequencies. The light that remains is a unique colour, specific to the conditions that created it. Starting with pure white light, the CMY cube can create dozens of unique colours.

Sliding the cube around on a surface can damage or start to peel the film off. When handling, try to not touch the edges or corners of the cube as to not damage the film. If the film does begin to peel at the edges, very carefully lightly press the film back against the cube. Some very light defects/scratching/peeling can occur to the cube during handmade production, this will not effect the educational use of the product.
