I’m not sure if blue (especially a medium to deep shade) is a color that’s capable of being a true neon, but there is definitely space for a very bright one in a neon collection. China Glaze Splish Splash (Summer Neons, Summer 2012) is a bright, vibrant blue with fine blue and purple shimmer:
Picture taken in sunlight. This applied well, though it wasn’t as pigmented I was expecting it to be, given that it’s not such a light shade; I needed three coats for full coverage. This doesn’t have a fluorescence like a neon yellow or green, but it is still quite bright. The shimmer does give it a certain glow, making the color look very vibrant (much more so than if this had been a creme, for example.) I think this is so aptly named; it does make me think of playing in the water in the summer (something I could probably use right now, as it’s been incredibly hot and humid lately.) I paired this with NARS Lal Mirchi on my toes.
