Hmmm, Rondelle is a very pale silver. Maybe Silver Fog Pigment, or Electra e/s (though Rondelle is a tiny bit lighter than Electra). For French Grey, one of the N Collection shadows was similar, but I forget which. FG is a taupe grey, but you could always use a medium grey color like Scene and get something similar. If I think of anything else, I will post here. Those are the closest I can think of right now.
