You are correct, they have not been covered yet. I've added a note in the "work in progress" section.

There are also LLRB trees that would be interesting to see compared within this framework. All the red-black trees are implemented as rank-balanced trees, so there is no concept of "color" exactly, but the authors do mention the left-leaning 2-3 rule and the left-leaning red-black rule -- I just haven't implemented those yet.
