OPI's Gargantuan Green Grape is a fabulous bright green. It's a strange kind of colour to describe as I don't see it as a mint shade. It is pale yet vibrant.
Whilst it didn't seem sheer to apply, you can still see some nail line after 2 coats. I think I may wear this over white next to see if that results in a cleaner finish.
Still, Gargantuan Green Grape is a perfect colour to wear this time of year.
