Lemon Fizz was introduced in the spring 2010 Up & Away collection, and I think it is/was added to the core collection since it is still very easy to find today. The shade is a pastel yellow, with a cream formula. The strong white undertone makes the shade look brighter then it really is, giving it an almost bleached neon pop. This shade is similar to SinfulColor Unicorn, but has the better, non-streaky formula.The thin formula isn't great but most yellows are tricky, as are pastel shades due to their white base, so for a combination of yellow and pastel I'm pleased with it. Like I've said the formula is thin [like most pastel creams], so it can pool up on the brush and flood the nails & cuticles, so be careful wiping off the excess. Some nails only take two coats for a flawless finish, but mostly this shade takes three coats for an opaque and largely even finish I find one thinner coat, followed by thicker coats when the first one is fully dry is best. A topcoat is a must-have with this shade, to fully even out the finish.Lemon Fizz is a nice polish overall, but China Glaze has just released a new collection (Color Is Magic My Little Pony) which has a pastel yellow in, and I prefer the formula on that shade as it evens out better.
