The colour is very difficult to describe, it is a blue, but with green shimmer and it has a metallic effect to it. Nothing over the top though, and the polish is absolutely stunning, especially in direct sunlight.
The formula was... actually a bit disappointing. It went on a bit patchy , dried too quickly and was difficult to work with. I would have expected more from a brand like Chanel.
However, the weartime was nice, four to five days.
Don't you just love this colour? It is amazing!
