I've always found what happens in the third dimension weird.

A 0-dimensional space needs up to: 1 color.

A 1-dimensional space needs up to: 2 colors.

A 2-dimensional space needs up to: 4 colors.

A 3-dimensional space needs up to: ∞ colors.

I can easily picture why a 3D space has no limit to the number of colors (personally I always imagine color blocks hanging in space connected to every other color block by bendable wires), but I don't quite understand why the pattern is that way.

Imagine the colours of a hypercube in 4-dimensional space!
