I wan’t to change the random color for the wires by a color picker to choose the color. I found a lot of them, but I wan’t a color picker that don’t have a lot of dependencies (like jquery, jqueryui, so on) , and don’t fill with mess my html.

So the option selected is  JsColor.

Now you can choose the color that the wire will have.
