This is 3 coats of colour and in some lights it is still ever so slightly see-through (though you would have to be peering at it with very beady eyes). You can notice the duochrome effect quite well here with the blue and gold shining through.
I love how subtle this polish is, yet when you actually stop to look at it, you see so much more than you'd ever have expected. I just keep looking and looking at it!
You can see here with backlighting that the gold is much more prominent than the blue, though the blue still peeks out from behind the gold, not wanting to be forgotten.
Finally for some close-up action of this beauty! I can't find a single thing not to love about this gorgeous polish.
As for the formula, it was a dream to apply even though the brush was so odd and will take a little getting used to. I should mention the 'New perfect stroke brush' that is in this polish is now in fact the "old perfect stroke brush". Any of the newer Nicole collections (like the 'Kardashian Kolors') have a much smaller and more normal brush. This brush is huge and paddle shaped and holds SOOO much polish that it's ridiculous. I have seen so many bad reviews of this brush and it was not actually anywhere near as bad as I was expecting, just different. For these swatches I used Essie 'Millionails' as my base coat and Essie 'Good To Go' as my top coat.
