Coloring the anodized surface

A. Please tell us what you're trying to make, and what alloy you're making it out of. All of the colors will be completely adherent because they are absorbed into the anodized layer. But some dyes are not suitable for exterior exposure because they will fade quickly, and some alloys will not accept anodizing and dye as well as others.

A. That is a good alloy for anodizing. 

There is a U.S. idiom, "this is like pulling teeth", which seems to apply here. You still haven't forthrightly answered me with what you are trying to do, which is causing this dialog to be of limited value and to drag on slowly and painfully :-) But in concept, dyeing anodized parts is simple: Immediately after anodizing them and before sealing them you immerse them in a warm water solution into which the dye has been dissolved. The dye is soaked up into the pores of the anodizing layer, and when you subsequently seal the parts, the dye stays locked in.

You can use simple fabric dyes for low quality results, or you can use proprietary dyes which have been tweaked to work optimally on anodized parts. In this case the dye supplier will be knowledgable about anodizing, and will have had much experience in running parts through the dye, and will include in his technical data sheet the temperature, pH, and other parameters that he has found to work optimally for that one particular dye. Good luck!
