6-Dimensional Hypercube of "Impossible" (Trichromatic) Binocular Color Combinations
A cube resolution that's more than 3x3x3 will probably cause some lags; be aware of that.
This 6D hypercube demonstrates that for every color you can see in your first eye, you can inflect that color with every color of your second eye. For example, there isn't a single "yellow", but a volume of many different kinds of yellows.
