Real Talk: Red Nailpolish

In Paris life is a lot slower, and I suddenly find I have time to do little things, like paint my nails something other than clear or cream. I've fallen into the red zone like Beyonce:
I *never* would have worn a red nail in NYC--no time to repaint! But now that I've tried it, I'm a quick convert--nothing screams sexy more than a bright red nail. Now I'm looking for even more shades to indulge in. I've got my eye on these:
1. Nars Nailpolish in Chinatown, $16. 2. Essie Nailpolish in Macks, $8. 3. Chanel Vamp Nail Polish, $20.
I'm clearly new to the colored nail thing: What are you fave red polishes?
