You can see the two others here.
Silver Slippers is a silvery/lilac foil. Not my favorite but not horrible.
Happy Birthday is a gorgeous purple with purple flecks/shimmer. This is like Milani Too Cool with that purple on purple action going on. Love this one!
Moonstruck is a lovely and elegant taupe creme with a hint of purple. KarenD did a great comparison that you should check out here.
