Hightlightening a branch of the tree.

In[216]:=

g = RootedEmbedding[MK2[MK1[Lf], Lf]]

In[217]:=

Coloring1 = {{1, 2}, {2, 3}, {1, 4}, EdgeColorPink} ; Coloring2 = {{1, 4}, EdgeColorHotPink} ;

The first coloring you write wins over the second one. If the first coloring is heavier and the second one lightier, the result is that the first coloring hightlights some part of the tree.

If the second coloring is empty, the first one is appplied.
