My wife and I are in the final stages of building our house. We have Rubio Monocoat in Slate Grey on our White Oak floors. We have White Oak door casings and box beams going in, which we would like to color match to the floor. Is it possible to "color match" a dye or stain to an existing color? Can you take a sample of the color you want somewhere and have it matched like you can do with paint? Would I be in more of a trial and error situation? Or, would it make more sense to just use the same finish on the casing and beams as the floor?
