Yes, WB can be used to capture a colour offset however the attenuated colours may become noisy and the colour offset may become difficult to control as it is dependent upon the target accuracy and the light under which it is used for WB. standard colour filters are a better way to go. Colour separation can be achieved during post processing assuming that you aren't intending to hand the file straight to a lab from the camera. In camera WB is a great tool however it has it's limitations For instance when shooting under tungsten lights most digicams will deliver better shadow detail, less distinct colour fringing and better colour balance in saturated image areas if an appropriate CC filter is employed prior to white balancing.
