I think you may need to rethink what you mean by "colouring the sound". The behaviour of the cartridge is determined by its mechanical and electrical construction, and must be influenced by the electrical input impedance of whatever it's connected to. "Coloration" is, therefore, unavoidable, at least at a theoretical level, because what you record will, of necessity, reflect this composite state of affairs. Perhaps the behaviour of the cartridge can be adequately characterized by an "output impedance", which will be both mechanical and electrical in composition and, presumably, known to the manufacturer. Perhaps this characterization can be deduced from the manufacturer's specification, or advice as regards the expected "input impedance" of the pre-amp. No doubt the type of cartridge would have a large role in determining it. Perhaps, also, you have have an adequate characterization of the actual input impedance of your chosen input device. Then you might be able to construct a digital filter that modifies your recorded input to reflect what it would have been had your input device had the same impedance that the manufacturer designed his cartridge to drive. Or any other input impedance of your choosing. Where does that get you ? I suspect that there's much to discover about what "real world" devices actually do, and the practical effects of that.
