Drawing an n-cube graph as bipartite

[Dragonfall]

What's the general rule for constructing such graphs? I mean actually drawing it on paper.

Start with the 1-cube, two points: and label them A and B. Now create 2 copies of the 1-cube and place A's and B's before each points label on the top and bottom copies, respectfully. Like this:

Also connect the points that have the same label other than the first letter (dashed-line in pic). And so on... Color the graph according to the first letter (or last).
