They all look duochromey/iridescent. Adina is by far the best, with a rich purple base and strong green/teal duochrome. Not a dupe of Ki, but similar feel to it. Best color I've seen in a while. Closest thing it comes to is Nubar Peacock Feathers, but it's not a dupe of that either. Very rich color.
Here's a couple quick shots of the swatches- hopefully I'll have the real thing to swatch soon! I know, they're blurry and glare-y, but I had like two seconds to take the pictures, sorry :(



They all look pretty in person, but I'm most excited about Adina. It's awesome.
