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.

The CMY Cube replica, also known as the "dichroic cube," is widely available on the internet. There are several distinctions between our cube and a replica cube. The typical counterfeit [found on Aliexpress, Ebay, Amazon, Walmart Marketplace and other drop-shipping websites] are generally sold for between $5 and $15 and are often under 1 inch or 20mm in size. Make sure you pay attention to the product description!

Unauthorised sellers can be found selling these counterfeit CMY Cubes all over the internet. These items are frequently not purchased from CMY Cubes or an authorised reseller. Instead, they are sourced from a variety of other sources without our consent. Due to the nature of the goods sold by unauthorised dealers and their business practices, products sold by unauthorised dealers are not entitled to the benefits of the CMY Cubes quality guarantee. CMY Cubes products sold by unauthorised vendors may be purchased on a secondary "gray" market and can therefore be pirated, faulty, refurbished, stolen, or even counterfeit goods.

We are constantly working to prevent businesses from taking advantage of consumers, but these activities continue.

Improving the Customer Experience
If your order includes more than one item - 1) that’s awesome, 2) depending on the type of items in your order and where they are coming from in our network, you may see that the order has been sent over multiple deliveries. This means that some of your items may arrive sooner than others, and it also means that you'll receive your order faster overall. And, of course, we always do our best to ensure your orders are consolidated into the fewest number of shipments possible.

So, if you see that your order has been split into multiple deliveries, don't be alarmed this is by design! It just means that we're working as hard as we can to get your order to you as soon as possible.

Typically 2-4 weeks worldwide.

These cubes are a bespoke handmade product and are fragile, they are for educational use and not a toy. 3 sides of the cube are coated in a fragile film and 3 sides are uncoated. 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.
