Guerlain Lou-Ling is a moderately cool-toned, very dark berry with a pearl finish. It is a limited edition nail lacquer that retails for $26.00 and contains 0.34 oz.
Guerlain Lou-Ling Nail Lacquer ($23.00 for 0.38 fl. oz.) is described as a "stunning plum for a spellbinding look." It's a deep berry-burgundy with strong red wine undertones and a very subtle dusting of subdued red shimmer. There are a lot of similar shades on the market--the biggest difference is going to be that smattering of shimmer, but it's not very visible in most lighting. MAC Gadabout Girl is darker. Deborah Lippmann Single Ladies is redder. MAC Blueblood is a smidgen darker, no shimmer. China Glaze Velvet Bow is a touch redder. Urban Decay Wrecked is similar but darker. MAC Purple Majesty is also a fair bit darker. Zoya Anja is fairly close (no shimmer, though). China Glaze Loft-y Ambitions is the closest--it has subtle shimmer and is a tiny bit lighter. Rescue Beauty Lounge Drifter is similar but has no shimmer.
Guerlain's newest nail lacquers are indispensable allies for accomplished femininity. The ultra-vibrant shades incorporate adhesive resins to offer a perfectly even sheen that lasts for days. Using each shade's extra-flat and widened brush, the easy-to-use formula imparts a shiny, daring and immaculate finish.
