Looks like that plugin works by aliasing the drawItem function of Window_Base, manually changing the hue of the contents of the window, and then drawing the icon.
That window has its own drawItem function, so the alias doesn't do anything for it specifically. I looked at it pretty quick and I think this should work, but I haven't tested it myself. Give it a try and if it causes an error or a crash or something, let me know and I might be able to fix it.
The main difficulty is that my window doesn't use many of the same properties to draw the items list as a window_base would, so his function might not work correctly here.
Either save that as a js file and import it below your other plugins, or paste that text directly into the icon hue plugin. As long as both plugins exist, it should work. I think.
