Haven't purchased one yet- I'm on a tight budget this week- but I took swatches of all the new Rouge Gs:
I couldn't get Rose Glacé to show up at all. There's a bit of shine at the left where I tried to. Other than that, l to r, you have: Geraldine, Geneva, Gaëtane, Gladys, Rose Grenat, Galiane To my eye rose grenat is the must-have, although it does look like a cross between Madame Batifole and Provocation, which were already fairly close. Gaëtane and Geneva are a little less opaque than the others.
