I found OPI Into The Night on sale a week ago, together with Just Spotted The Lizzard. Loved the blue color, a true blue in my mind, with a nice, subdued shimmer. No purple tint, no green tint, just blue. That is not shown in the photos, the blue seems to lean an micropart of an inch to green. But ok, the color IS ok in the photos too, but not as nice as the color IRL.
It's a real sheer polish so I used IsaDora City Khaki (beige-grey) as "undies", and two coats of Into The Night. Easy to apply.
