Recursion example. A possible scenario encountered by the subcoloring recursion. The letters a, b, c and d represent the presence of leaves with those taxonomic labels; asssume these taxonomic labels do not occur elsewhere in the tree. The positions of colors b and c shows that this coloring is not convex, and a recursive subcoloring algorithm must decide at x in which subtrees to allow the b and c colors.
