Lincoln Park After Dark was my very first OPI polish. :) It's a very, very dark purple (almost black). I loved wearing this when I was in high school because it was dark enough to get attention but it wasn't as drastic as wearing black. I needed two coats, but I noticed some streaks when the sun was shining directly on my nails. Not really a big deal unless you're really obsessive about it. This first photo is in bright, direct sunlight.
This photo is in sunlight as well, but it's more diffused than the first. You can tell how dark LPAD is in both of these photos though; the first coat shows up as a rich purple/burgundy, then the second coat is just pure darkness. After my two coats were dry, I taped off my tips and used Essie Matte About You for the awesome contrast in finish that I love so much. I don't think I'm as crazy about this color as I used to be :/ Oh well!
