This is my first time to even see this thread, but excellent work!

I am at a total loss as to how color is added to alum by way of anodizing it. All I know is the word "anodize" comes from anode (negative end) versus cathode (positive end). This of course means elctricity is involved. To anodize the part, do you run a current from one end of it and apply the anode-affinite dye to the other end?

How is it done and how can the average RC fan like me do it at home? I have a moderate degree of skill in art and would love to try my hand at coloring by anodizing some parts!
