This manicure allowed me to compare China Glaze For Audrey and OPI Mermaid's Tears. The OPI was used for the accent nail. You can see the difference between the 2 colors easily. Mermaid's Tears leans greener than For Audrey. I actually like both colors very well and both applied nicely. I then used the OPI Silver Shatter on the accent nail and just love the combination!
