Peace & Love & OPI is probably one of the best polishes to come out of OPI's San Francisco collection. It is a duochrome colour a slate grey metallic base with pigments that flash an aqua/green in bright light and a pinky purple in dimmer light. It is very pretty and brings to mind images of an oil slick. It is unique to my collection. The formula is a little thinner than my other OPIs, though I still managed to get it to become opaque in two coats, you need to apply quite carefully though in order to avoid bald spots. It dries with some visible brush strokes, but for the most part is self-levelling. I would recommend applying carefully though, in straight lines to minimise brush strokes. It dries quickly and to a shiny finish, though applying topcoat really emphasises the duochrome effect. I get around 4 days wear from this polish when paired with base and top coat, so slightly less than my other OPIs. I imagine this may be due to the thinner formula. Regardless this is a very pretty shade of duochrome polish and I am happy to recommend it to anyone. I believe it would be universally flattering on all skin tones.

I chose this shade of OPI when I got my nails done recently, and I absolutely fell in love with the unique duochrome nature of it. In some light, it looks like a metallic charcoal. Then, light hits my nails from another source or angle, and it looks, green, blue, aqua, pink, purple, or even a slightly orange-rust hue! I've never seen anything else like it! I was so in love with this color that I bought a bottle online and decided that it will be my new signature nail color. I would recommend this to anyone and would buy it again and again. The picture above doesn't do the shade justice at all, IMO.

I've recently started getting into nail polish more and this was my first time trying OPI. It requires two coats to be opaque and it's a really nice metallic grey, green and purple shade. It sort of resembles an oil slick design. I did find this to be quite expensive at $19.95 but I live in Australia so I assume it is cheaper in other countries. Wears really well and can't see the brush strokes. Will buy again

This is a very unique color and if applied with one coat or 2 looks completely different. A grey-base with purple to green duo-chrome over it. Lovely and unique. Edgy. Love it.

I like the changing nature of these types of polishes but this one did nothing for my skin tone. The base is a steel grey but it changes to a flash of green or purple depending on what type of light you are in or how you hold your hand. Good formula, no visible brush strokes. A two coater. I will not repurchase.
