Shimmery Seafoam and Abalone are two amazing colors for summer. These are probably my favorite shades in this list, but I have always been super partial to blue-greens and anything shimmery. If you want your nails to be mermaid inspired then either one of these colors is definitely what you need. You can even make scale designs with them for a full summer mermaid look. Get the 2 colors from NAISINC London for about $15.00.
