Today i used 'My Personal Serpent" by OPI for Sephora ( i do believe this particular color has been discontinued but the same look can be easily replicated with any similar shade). This particular shade is a very dark grayish blue and looks almost black when applied on the nail. I followed it applying a coat of "Only Gold for Me" also by OPI for Sephora. I kind of like the pairing of the two. Hope you do too!
