I have a RI Montana and am actually glad it has no shimmer because it's such a strong color any way.
blues: *the Bleu Infini has shimmer, it's a dark rich navy, looks almost black in some light
*the Grand Bleu is a royal-ocean blue and has some shimmer to it
*you can check out the Bleu Nuit (teal blue) and the Bleu Lagoon (turquoise) also - i haven't seen those IRL
*and there is the new Blueberry color too, it looks gorgeous on the web-site but you have to be careful going from just the LV site because the
colors don't match up to what they look like IRL.
reds: i haven't seen the Griotte (dark wine red), Rose Grenadine (red w/ pinkish tone) or the Cherry IRL but the Pomme has shimmer, it's a gorgeous apple red (one of my favorite vernis colors of all time).
while most of the vernis colors do have shimmer to them i'm not sure one color has more shimmer than others, i just think they either have it or don't.
