Get Grasshopper's preview colors and materials

Is it possible to get the user-defined colors and materials in Grasshopper’s preview settings?

Normally, these are passed on the the preview methods of parameters, but I have a more complicated system where I would like to be able to query these colors regardless of what is passed to the preview method.

To get/set colors, you could use this

var doc = OnPingDocument();
var previewColour = doc.PreviewColour;
var previewColourSelected = doc.PreviewColourSelected;

I don’t quite know in which context you need this. But you could also in case of a component do something like this:

private Brep brep;

public override void DrawViewportWires(IGH_PreviewArgs args)
  {
    base.DrawViewportWires(args);

   var someCustomMaterial = new DisplayMaterial(customColor);
   args.Display.DrawBrepShaded(brep, someCustomMaterial );
  }

Don’t know if that is what you’re looking for, but if so I can give you a bit more in dept example.
