Marek, I don't understand that; you can already get rich and dead neutral
blacks with (NH4)2[PdCl4] or Li2PdCl4, "w/o adding any Pt and/or gold
chloride"?

Regards,
Loris.

By the time I could get really nice and neutral black with POP palladium and
gold, I was also getting a pink stain in the highlights, very unappealing.
The pink is a result of colloidal gold being made during development. The
more gold, the reacher the blacks and worse pink stain, the contrast of the
mix changes as well. AT the end I did not feel I could produce images that
were techincally accomplished and do it in a reliable fashion

If you are after pure rich black pure platinum is the way to go.
