    I have found that you have to anodize to a full 1mil coating thickness for a deep black color. Use the 720 calculator.
    Although the black dyes very easily, I have not had good results dyeing at room temperature.

    The dye works best at 140 degrees. Some have said they use it at room temp but the problem of a dark blue color usually is old dye or too thin of a anodic coating. Since it is an occasional problem and seeing your other post I would think that too thin a coating would be the most likely cause. Do you use the 720 rule? What CD do you use? What PS are you using?
