Here's one we've all seen a bajillion times - Chanel Peridot. This is a gold/green duochrome metallic. I was on the fence for a long time regarding Peridot - I couldn't decide if I wanted it or not. Some photos were fabulous and others were just "meh". My husband, the enabler, said "just buy it anyway, if you hate it, ebay it".
Basecoat: Gelous (1 coat)
Color: Chanel Peridot (2 coats!)
Topcoat: David (1 coat)
Gorgeous, right? Still, this polish seems to be - on me, anyway - mostly gold. The green is not nearly as prominent as it is in the photos, mostly because I don't walk around with my hand in front of my face so I can see it.
This polish nearly applied itself - it was that nice. Went exactly where I wanted it, minimal cleanup, opaque and smooth in TWO coats! It is a tiny bit brush-stroke-y, but I think a lot of polishes this metallic will have that.
