^^ The rouge allure is my favorite formula. I don't have Mystery -- but I have seen reviews where people compared it to MAC's "O" l/s.
Out of the RA formula, I have Instinctive (golden peach), Mythic (nude), Imagination (gorgeous medium pink), Joyeuse (bright pink -- LE Asia collecton -- but the ladies have found out that it is coming to Nordstrom soon), Confidentielle (Peachy pink), and Comedia (another gorgeous pink -- cool).
I have on my list to check out: Incognito (warm med. pink), Adorable (bright plum pink), Desirable (warm hot pink), Exquise, and Ardente (warm pink). The online swatches look absolutely nothing like the actual product -- so hopefully the descriptions help a bit!
