Ready, Fête, Go is a holographic teal-green nail lacquer from OPI's Celebration collection (Holiday 2021), named for the French word for "party." Unlike a standard shimmer or glitter, it uses aluminum powder pigment for a true linear-holographic effect, throwing rainbow flare across the teal base in direct light rather than a soft glow. Apply over a base coat and finish with top coat for a manicure that holds up to about a week before chipping.
