Stay Out All Bright is a vivid yellow nail lacquer with a crème finish, released as part of OPI's Summer Make The Rules collection. OPI's own product page describes it as an opaque, true yellow rather than a pastel or muted tone.
The crème formula lays down as a flat, glossy layer of color with no shimmer or glitter mixed in, which keeps the yellow reading as solid and uniform once sealed under a top coat. As with other bright, opaque yellows, any unevenness in the nail bed or ridges will show more readily than it would under a darker polish, so smooth, thin coats matter more than usual. It's OPI's standard air-dry Nail Lacquer — not a soak-off gel — applied over a base coat and top coat and removed with ordinary acetone-based remover.
