I want to prove any AVL tree can be turnt into a red-black tree by coloring nodes appropriately. Let h be the height of a subtree of an AVL tree. It is given that such a coloring is constrained by these cases: h even black height = h 2 + 1, root node black. h odd black height = h + 1 2, root node red. After that the root node is colored black.

13.1 Properties of red-black trees - CLRS Solutions

WebRed-black trees are relatively simple balanced binary tree data structure. The idea is to strengthen the representation invariant so a tree has height logarithmic in the number of nodes \(n\). To help enforce the invariant, we color each node of the tree either red or black. Where it matters, we consider the color of an empty tree to be black.
