Just became an owner of a Kubota L4600 with an Ansung front end loader. There are no color codes on the hoses at the quik couplers at the joystick control valve. I am going to color code them so my question is are the colors just to not to cross hoses or are the colors standardized to specific functions of the boom or bucket. If there is a standard, I would appreciate that info from someone. I am new here and am already very impressed with the wealth of knowledge on this forum. Thanks much in advance.
