Envision the vibrant glide of rainbow iridescence, captured on duck-shaped nails, where a kaleidoscope of colors shifts with every flick of the fingers. Adorn each nail with playful patterns of holographic stars and tiny shimmering moons. Let the base explore a gradient fusion from electric mint to cosmic purple, echoing the mystique of a night sky mid-celebration. Tiny gem accents punctuate each fingertip, adding a sprinkle of lavish charm without overshadowing the celestial theme. For a finishing touch, apply a high-gloss top coat to play up the dynamic angles that duck nails shape offers.
