Paint different path on the tree with forest package

I need to paint a different path on the tree to figure two different situations that happen on the tree.
In particular, I’m able to figure the travers tree with a forest, as the figure below, and this will figure my cases from root -> leaf.

But I need also to figure the cases from the leaf -> root with different colors and different arrows that point from child to parent and I don’t know where to start.
