Metal Anodization  

++

I would appreciate you help me on this need. I've seen your web site and it makes me write for help. My question is about aluminium anodization. How can I get a light violet color while anodizing aluminium? Is there any lamp reflector or another thing I can use? Thank you a lot for your time.

I did not understand the reference to a lamp reflector, although aluminum is often bright dipped and then anodized as a way of making lamp reflectors. The way to get a light purple color would be to buy a light purple dye, and to dye the parts in between sulfuric acid anodizing and sealing.
