I have been adding color, Alkanet root powder, to my finish for some time now. I agree completely that if you are cutting back at all, that is the way to go in order to get a nice even color.
I have used a rotten stone slurry rubbed in with root powder and Daly's, it gives a wonderful finish and is indeed hard on checkering tools.
I find a few coats of Boiled Linseed Oil with Alkanet root powder giving me a darker color than if I just put the root powder in Daly's.
Always interested in hearing how other's go about things.
