There are three colours in the new Cocktail Colours collection: Shirley Temple, Baby Bellini, and Hawaiian Punch. The label describes these as "One coat nail polishes. Dries in less than 60 seconds." Firstly, these are NOT one coat colours. One coat was very sheer on all of these, and on the purple (Baby Bellini) also very streaky. These swatches are all two coats.
This is Shirley Temple, a bright orange glass fleck polish. This is a much paler orange than many of my other orange polishes, but still nice and vibrant.
Next up is Hawaiian Punch, a bright fuschia pinky red. It is definitely more pink than red in real life, but it is leaning red in the photos, which I can't capture easily in photos.
I think this is pretty, and the sparkle is nice.
Last is the purple, Baby Bellini. I don't understand this name at all! Bellinis are a pretty pale peachy colour, not purple! I think this is my favourite of the three.
I don't have as many purple polishes as I do orange or red/pink, so maybe it's more unique in my collection.
These are all pretty, and the glass fleck is sparkly and quite pronounced. However, I just don't think they're that unique. There are plenty of other, better, glass flecks out there, and I have colours that are similar (but nicer) than these, such as China Glaze Riveting, or OPI Be a Dahlia Won't You... These are cheaper, and more easily available in the UK (these are £3.99 each i Boots, and are currently on 3-for-2) so they may well be a better option for many people. I think they're pretty, and I'm sure I'll wear them, however, I'm really not blown away by them.
