OCC Automaton Nail Lacquer ($10.00 for 0.50 fl. oz.) is described as a “24K gold with red/green duochrome [with a Metallic finish].” It’s a brightened, sunshine yellow with warm, yellow-red undertones and very fine micro-shimmer that shifts from a coppery-red to a murky green. I tried so hard to capture the duochrome, but it’s really subtle, and despite dozens of photos, no luck. After two coats, there was still visible nail line, and I’d describe the coverage as semi-opaque. It applied evenly, and there weren’t any brush strokes even though it is a more metallic finish. NARS Kismet (LE, $19.00) is darker, more coppery. See comparison swatches.
