Starting from the top, we have Grass Slipper on my index finger. It's ever so slightly darker and less yellow than the Who the Shrek Are You? on my middle finger. On my ring and pinky, it's Lucky in Love Lime and Wicked FUN (why the caps, Piggy Polish--is this an acronym for something?) , but it might as well be the reverse, as I can't tell the two apart. They're lighter and a bit more yellow than the first two limes. In slightly less bright light, the differences show up somewhat less strongly:
Since I only needed two coats of the Sally Hansen to three for all the others, and I think the shade is slightly more flattering on my skintone, that's my top pick of these four.
