I use warsaw chemicals and apply triple foam low ph conditioner on top of my presoak. The problem is warsaw doesn't really make a low ph conditioner so I am using their 701 wave curtain bath which comes in three colors, white, yellow, and pink. This stuff works well through the triplefoam heads on my Razor. The issue is the 3 colors they have the white and yellow pretty much cancel each other out and all you see is pink and pretty much a yellowish white. I would like to add some color to the white to make it blue or something a little different. Where would I find the coloring? Would food coloring work? I have contacted Warsaw chemical about my situation and all they have to offer is they have triple foam polish, which I don't want. I want low PH conditioner.
