I am a nail-polish fanatic, and LASplash makes some great bright and unique colours. They are pretty pigmented, I can usually get away with two coats for them to be opaque. Staying power is pretty good too. If you're like me and you go through a thousand colours on your nails in the summertime, you have met your match.
Note: The colour I've shown here is not in the swatch display list, it's called Dolphin's Smile.
