Bobbi Brown Black Pearl Shimmer Lip Gloss ($23.00 for 0.24 fl. oz.) is described as a “dusty mauve.” It’s a gray-tinged mauve with a hint of plumminess and pale mauve shimmer. What it does on my lips is darken the natural lip color, give it a cool-toned cast, and add a healthy dosage of pale mauve shimmer. Chanel Pleasing is warmer, less plum. Urban Decay Perversion is a bit darker.
