Guerlain #31 is a very warm-toned, very dark pink with a satin finish. It is a permanent lipstick that retails for $33.00 and contains 0.12 oz.
Guerlain #31 Rouge G de Guerlain Matte Lip Color ($33.00 for 0.12 oz.) is a muted, medium-dark rosy pink with strong, warm undertones and a satin finish. It had nearly opaque color payoff that adhered evenly and smoothly across my lips without tugging or dragging during application.
The lipstick had a lightweight, more velvety consistency so it felt like it glided with ease over my lips but didn't feel slippery or "wet" during wear. This shade applied better than some, but it just didn't lay as smoothly nor was as forgiving of my lip lines/minor lip texture imperfections compared to the original range of Rouge Gs (and this formula is supposed to do the same with respect to smoothing). The upside was that the color didn't settle into my lip lines further while worn, so it was only visible in the close-up photos but not in person. It lasted well for five hours and felt lightly hydrating while worn.
