上述代码未对源节点和目标节点应用正确的颜色。

创建连接时可以使用以下方法设置连接颜色

jsPlumb.bind("jsPlumbConnection", function (conn) {
   var source = conn.source;
   var target = conn.target;

   conn.connection.setPaintStyle({
             strokeStyle: getConnectionColor(source, target), 
             lineWidth: 3
   });                
});

实现getConnectionColor（source，target）方法，根据源和目标获取颜色
