Cover Girl Emerald Blaze is a name that I find fitting for this nail color. It has this beautiful metallic sheen to it and is slightly duochrome. As you can see, certain area have darker, cooler tone, olive green color to it, giving this polish more dimension.
I picked this up at Walgreens about a month ago because I thought it looked pretty but I didn't realize until I got home that I may already have a dupe for it.
So the dupe that I'm talking about is OPI Green On The Runway. As you can see, they look pretty identical. I couldn't tear them apart when I have them swatched next to each other.
There is however a difference in the formula. The OPI formula is thinner and easier to apply and you'd need 3 coats for opacity. The Cover Girl one is thicker and you'll have to be more careful how you apply it because it may create bald spot in some area. It's workable and two coats is enough to reach opacity.
I still prefer the smoother and thinner formula of OPI as it is easier to work with but Cover Girl Emerald Blaze is definitely a good dupe if you want something similar but cheaper.
