Sadly no. Type III anodizing is almost impossible to dye and the setup is incredibly expensive as the acid bath needs to be maintained at 35F at all times. Since I can get a anodized layer similar to type III with my current setup but larger cells, I saw no need to go the extra cost.
See really the ONLY difference between Type II (what I do) and Type III is the Cell size. In type III the cells are smaller so they don't readily accept dyes, this means you can only dye it greyish/black. The thickness of the anodized layer can be controlled by the amount of time and the amount of current supplied to the part. I can make an anodized layer almost as hard as type III in a type II that will allow for dying.
Hope that helps.
