    Ahhh, the most common mistake rears its lovely head! The process is
    called anodizing and the work/color always appears at the Anode(+).
    When you are working with a brush(Cathode[-]) the object being
    colored (Anode[+]) is outside the bath. The electrolyte is on the
    brush in contact with the metal ferrule(Cathode[-]). The object is
    connected to the Anode(+). Look at the brush is a miniature portable
    bath. Instead of the container and metal strip the hairs of the
    brush hold the electrolyte and they are in contact with the
    Cathode(-)/metal ferrule. Don't worry, I hook them up backwards at
    some point in every workshop and I have been doing that for 26 years!
