This is the Pre-Color that I use on Ash to produce my black charcoal finish. Rubio Monocoat has several Pre-Colors; I stock this one that I use on my Charcoal Ash finish, although you can contact me for other colors. The first photo is the product that is included in this purchase, and the rest of the photos are from my own projects using Intense Black Precolor (This product), followed by Charcoal Oil Plus 2C, finally followed by Maintenance Oil on white Ash.
