These are what they look like in the bottle:
Cheyne Walk is a purple metallic that shows flashes of a somewhat murky olive colour. The combination is interesting, but the colour shift is not as pronounced as in Stratford.
This is probably the closest these polishes get to a "mirror" effect, but I personally classify them as a metallic. When I think of a true mirror effect I always envision the gold and silver Minx manicures. Sadly, this isn't an effect achievable through nail polish yet (or else I strongly suspect I would wear nothing else).
The colour shift in Cheyne Walk is most accurately captured in these last two pictures.
Stratford is a light champagne gold metallic with strong flashes of peach, yellow, pink, and at times, pale green. Out of the two, it's my favourite; the multichrome shift seems stronger in this than in Cheyne Walk, which I like.
In direct light (as seen above), some very minor brushstrokes might become evident, but I definitely don't classify this as a brushstroke-prone polish. Overall I quite like the finish.
Stratford really looks fascinating in certain lights and at certain angles; in the picture above you can really see the range of colour in this lacquer.
These last two pictures are truest to how Stratford looks the majority of the time: a smooth shiny pale gold, with touches of yellow and peach.
Overall I'm happy I ordered these. I'm a huge fan of any chrome, metallic, or duochrome finish on a polish, so these made me quite happy. I also suspect that these might be somewhat close to the Deborah Lippmann Mirrored Chrome Nail Lacquer collection that recently came out. In particular Stratford seems kind of similar to "Sugar Daddy" from that release. I don't have them to compare, though- I'm just going by some of the swatches I've seen online. Does anyone have an opinion on possible similarities between these?
