Anyone who wants a bold, high-shine yellow manicure or pedicure for warm-weather wear, whether applied at home or in a salon.

Suited to people comfortable with a full base-coat/two-coat/top-coat routine, since shimmer polishes generally need more than one coat for even opacity.

A reasonable pick for anyone specifically looking for a vegan, 3-free lacquer rather than one making an all-natural claim.

What sets this shade apart from a plain yellow creme polish is the fine shimmer suspended in the lacquer, which catches light and adds depth without going glittery or textured. It's built on OPI's long-standing 3-free lacquer base, so the trade-off some people look for -- avoiding formaldehyde, toluene, and DBP -- is already built in without switching to a specialty 'clean' brand.

OPI recommends full nail prep before applying color: push back cuticles, trim and file nails to shape, buff the surface, and wipe with isopropyl alcohol or a similar nail cleanser to remove oils.

Shake the bottle well before each use to remix the pigment.

• Apply OPI Natural Nail Base Coat in a thin layer, sealing the free edge first, and let it dry 1-2 minutes.
• Apply Paintin' on Sunshine! the same way -- edge first, then a thin layer over the nail -- and let dry 1-2 minutes.
• Repeat with a second thin coat of lacquer for full opacity.
• Finish with OPI Top Coat, sealing the edge first, and let dry 1-2 minutes before touching.

Pros

• 3-free and vegan formulation
• Pro-Wide brush covers more of the nail per stroke, reducing visible brush strokes on flat nail areas
• Rated for up to 7 days of wear with OPI's base coat/top coat system
• Part of a coordinated seasonal collection, so matching OPI GelColor and dip powder versions of the shade exist

Cons

• Shimmer finishes can show streaking if applied too thickly in one coat, so thin, even coats matter more than with a creme polish
• The rated 7-day wear assumes use of OPI's specific base and top coat, not the color coat alone
• As a seasonal collection shade, long-term availability may be more limited than a core-line OPI color
