The tonal range of a palladium or platinum toned kallitypes, with no contrast controls, is almost identical to that of straight palladium, i.e. an exposure scale of around 1.85. And you can use the same contrast controls that work with palladium, including dichromate and Na2. The color of toned kallitypes is almost neutral, ranging from warm black when toning with platinum to just slightly warmer when toning with palladium. The very warm colors that you can get by developing regular palladiums in warm potassium oxalate are not as easily obtained with toned kallitypes.
