Brown and Other Colored Soaps and Creams

I am not sure what you mean when you say "I have not seen any listings like that".  If you mean listings from the manufacture that the soap stains yes there are.  They are including that in the soap description so the potential buyer will know.  The biggest problem is not the stained towels because it typically washes out but it may stain a natural hair brush.  However, if you use a synthetic brush there is not problem.

Yeah a warning sounds good to me.  When I just received the Drunken Goat from Mickey Lee Soapworks, it was an intense dark soap.  It smells INCREDIBLE though.  Unfortunately, I own one synthetic and the other 10 brushes I have are all 2-band badger brushes with very white tips.  So I'm not going to be able to use those brushes with this soap, or some other brown ones I have (Pannacrema Nuavia Blu).  I need to pick up another synthetic or a cheap boar to use with these I guess.

Have had Pannacreama Blue and Rossa for over a year.  I used Blu yesterday it does not stain because it lathers white.  Not all dark brown soap stains.

Blu stained my towel before and after that, I decided to quit using 2-band brushes with it. My guess? Not all blu is the same, because my Blu, has a tan lather to it. The Rossa is fine, but yeah, white towels have been stained by Blu before with my use case.

When I say white it does not have to look like wipped cream. It is an off white. I have not heard anyone complaining about Blu staining a towel. Maybe others can comment. When the towel is washed in a washingmachine doe the color wash out?

It did wash out. I just figured, sustained use on a white tipped brush might be a bad idea? I'm overly cautious since these brushes cost an arm and a leg.

Now the Drunken Goat on the other hand? Dark brown lather, very different. Not sure how it would turn out but again, I'm just going to use a junk brush with it.

Contact the manufacturer and ask them if it will stain.
