What colours are available with Alochroming?

I have a component that requires to be an anodised black colour, but part of the inside must be conductive. I thought one may be able to mask the conductive area whilst anodising, but I've been told that this is not possible. Then I thought of Alochroming, so I need to know if you can Alochrom black?

Thanks in advance,

Masking areas from anodize is possible and done every day!
Some masking requirements are more difficult than others but I have yet to have a job come in that was impossible!
