Ozotic. Any lacquer lunatic that isn't living under a rock has at least seen swatches of their divine polishes. If you are lucky enough to live in Australia, where they are made, or willing to pay high postage prices you probably have at least one shade.
When I heard that the multichrome 500 series was being discontinued I stocked up. 520 is a dark red, orange and gold colour shifting beauty. In direct, bright light it mostly appears a lovely burnt orange but in indirect sunlight there are so many facets of colour it's distracting, in a great way.
The picture below is in indirect sunlight.
As always, this is two coats of 520 layered over a dark base. I used China Glaze - Midnight Ride this time as it is opaque in one coat and one of those 'almost always looks black' shades.
