What are the common issues encountered when implementing a red-black tree, and how can one effectively address the red-black tree bug?

Common issues encountered when implementing a red-black tree include incorrect node coloring, violation of red-black tree properties, and incorrect rotations. To effectively address red-black tree bugs, one can carefully follow the red-black tree insertion and deletion algorithms, ensure proper node coloring, and validate the tree structure after each operation to maintain balance and adherence to red-black tree properties.
