Juno is from Zoya's Utopia collection. I lurve the Utopia collection, there are some really awesome colors there. I have Juno and Akyra, and I want Irene. I'm loving the name Juno for this purple. In Greek mythology (or rather, Roman, since this is the Roman name), Hera is the wife of Zeus, king of the gods. Hera and Zeus translate to Juno and Jupiter in Roman mythology. :) So, a purple totally makes sense for a queen of the gods. Very royal.
This particular purple is pretty fabulous. Bright yet rich, and very fun. It's pretty reflective, making me think it's metallic or frosty at times, but it's not.
Application was great, as is usual with Zoya. My problem with this one is that it chips in, oh, 12 hours. Yeah, that's not so great. But if you're willing to put up with some wear issues, this polish is fantabulous and you should definately buy it. :)
