I have another thought on sanding. I have a feeling that the chemicals creating the color in Pene eggs is imbedded in the egg, maybe not to the extent of blue eggs but I can rub a lot and not scrape any off, unlike most other brown eggs.
Also I occasionally get plum eggs. I also think I figured this out. The egg is supposed to be a dark reddish brown. So if the brown is missing I think that all that's left is the plum.
