Poseidon caught my eye as soon as I saw photos of it on the Shades of Phoenix facebook page. I was lucky to snag a bottle on launch day, and lucky I did because this one sold out quickly! Poseidon has a mix of turquoise hex glitter, blue square glitter and white bar glitter in a green jelly base. The white bar glitter gets lots in the green base so unless it's sitting on top it just looks green. I loved this from the first photos I saw of it and I loved it even more in real life. Currently Shades Of Phoenix polishes are only available within Australia. If you can get your hands on them seriously consider this one!
