dichroic glass

How would I set up a dichroic glass pane, which is changing colour dependant on viewing angle and also surface caustics are in the opposite colour than transmission dependant in light angle?

Use facing ratio as the mix amount of an "mix-" or "layer-" rgb node. I am not sure about the caustics, however. Are you talking about caustics or surface reflections, though?
