Clumsy wording of me. "Noticeable discoloration" actually meant to say that MCC 110 reacts well to selenium (change in colour as well as darkening of darks).

So lots of combos of paper and toners to try- could fill the rest of my life.
I may try MCC 110 with only sulfide also, even though I don't expect much of it. But maybe "not much" is exactly the subtle result Roger seems good at, and his stuff is excellent like you say.
