Well, being as cobalt blue is supposed to be one of the "it" colors this spring, I decided to pick up Blue Streak when I went to Ulta and they had their polishes at 2/$4. This is a neat and vibrant blue that looks great in sunlight and is a lovely pop of color for any outfit. Two coats of super pigmented polish and Blue streak looks perfect. This is a blue that is on the cooler range and has more white than black in the base, making it cobalt rather than navy or royal blue.
Two coats Ulta Blue Streak, one coat Seche topcoat.
