I have actually owned "Cafe Au Lait" for almost as long as I have owned MAC "Abalone Shell" (which is what- almost 3 years now?). I let my sister borrow it for a long time and when she gave it back to me I noticed that it really did resemble "Abalone Shell." But since I really don't like the Sally Hansen Salon Manicure line, I threw it into the back of my polish collection and forgot about it.
Since I made the 2013 New Years Resolution to buy less polish, I have been digging through my collection and stumbled across "Cafe Au Lait." I put it next to "Abalone Shell" and was amazed how close the two colors are. Almost dupable from viewing through the bottle.
