Chameleon is such an under-appreciated brand. They're a very small line, but they have some gorgeous duochromes. Corona is a mauve foil with blue duochrome. I wish that I could have got better pictures of the blue, but believe me, it's there. The angle of the bottom picture shows a brighter fuchsia-pink, but you can't really see it in the picture... I tried!
The finish is a foil, but it gives kind of a rough finish on the nails. It's pretty, but it's a little difficult to work with. This was 3 coats, I believe. All in all, I recommend this nail polish, and if you're a fan of duochromes, this is a good drugstore brand for them.
I've never really heard anyone else talk about this brand; have you tried it?
