My understanding is that wood containing tannins will color darker, almost black. For walnut, I'd avoid aqua fortis, and use an alcohol based stain to tint the wood. I like plain varnish alone.

Around here folks call iron- saturated aquafortis, "aquafortis". Iron-saturated aquafortis will turn walnut black. Nitric acid which does not have iron in it but is correctly called aquafortis can be used on walnut with success.

I use my homemade Nitrate of Iron Stain(Nitric acid and water with iron dissolved into it)regularly on Walnut.I've provided link to two rifles done in this manner.I find that I get nice golden undertones and greater contrast in any figure in the wood. I do two coats blushing between coats.I let it dry completely before blushing.
