Good article.
Note that where the author says "900 amps per minute per square foot" he
really means "900 amp-minutes per square foot". His calculations are
correct, just the description is wrong.
Also, to get the corrosion resistance of anodizing, you must "seal the
pores" whether you dye the part or not. He mentions this, I just wanted to
emphasize the point.
Last, I've heard you can use ordinary Rit wool clothing dye from the grocery
store. Haven't tried any of it myself, so I don't know for sure.
There are lots more comments on anodizing and coloring aluminum (but no
pretty pictures) at
