AFAIK, wet plate collodion has never been sensitized to anything other than blue. It is pretty much impossible to do with the technology invented for silver gelatin.
However, you might find a way if you are willing to experiment.
The method is very simple. You add the dye just before coating the silver halide on a plate or film. Usually, you hold the warm emulsion for 15 minutes. Then you ad any finals. Then you coat.
The amount of dye is based on grain size and can vary from 10 - 100 mg for every mole of Silver ion present. That must be determined by trial and error. Once set, it is firm at that level.
