The highlight for the path tool is related to the layer color and each layer comes with it own color.
You can change the color of the layer double clicking a non active part of that layer in the layers panel.
Double click the color square and you get a picker pick a color
Layers can have any color and so can sublayers and that would be the only waay to control the color
A few of the things that might be worth knowing/realizing:
1) It is best to use the smallest possible number of Anchor Point, placed where they have the greatest effect on the shape, to get the smoothest and cleanest paths; in this connexion it is important to think ahead to enable the right continuation.
2) You may avoid some try and fail, then Undo, when you ClickDrag a new Anchor Point with Handles, by pressing the Spacebar which allows you to move the Anchor Point about while the Handles are freezed.
Others may add other suggestions.
