Laura Mercier Cobalt is a very cool-toned, dark blue with a matte finish. It is a permanent eyeliner that retails for $24.00 and contains 0.04 oz.
Laura Mercier Cobalt Longwear Eye Pencil ($24.00 for 0.04 oz.) is a medium, navy blue--there's just a little brightness so it's not a full-on navy blue. If it were actually intensely pigmented, it would be really quite a rich shade of blue with a nice balance between bright and dark, so it wouldn't read neon on the lash line but add more pop than something more muted. The consistency was still creamy, but it was sheer and hard to build up the color even when I went back and forth. It seemed to last about seven hours on the lash line, and then it looked thinner but not smudged or migrated, after eight hours. Sephora My Boyfriend's Jeans has slight pearl and is brighter. Urban Decay Chaos is brighter. See comparison swatches.
