Color an element of Unity hierarchy

Simple question, am I able to color an element of my hierarchy to make it stand out against
the other element in the hierarchy.

For instance prefabs in the hierarchy are blue, I want to change the color of one single element to orange?

Simple answer: No, you cannot currently do that.
